A crazy weekend containing some unforeseen upsets has led to some teams getting knocked down on the bubble and others that appeared to be out of the bubble being moved up.
Many top teams lost in the past few days, sending some of those higher seeds from the last bracketology further down.
With the season coming closer to an end, I will probably start updating this bracketology a little more often.
Kansas (Big 12), Kentucky (SEC), Duke (ACC), Villanova (Big East)
Kansas is yet to lose in the Big 12, which is arguably the toughest conference in college basketball. The Jayhawks' magic number for a Big 12 title is three.
Kentucky has won five straight games. The Wildcats play four of their final six games on the road.
Duke has won four straight games and six straight ACC games.
Villanova is still a one seed because it is in first place in the Big East. The loss to UConn really hurt the Wildcats, but they have so many big wins that they are inarguably one of the top teams in the nation.
Syracuse, Ohio State (Big Ten), Kansas State, Purdue
Syracuse had an 11-game winning streak snapped by Louisville. Surprisingly, both of Syracuse's losses this season have come at home.
Ohio State, led by Evan Turner, won their sixth straight game. The last five of these wins have been by double digits.
Kansas State has won three straight games. The Wildcats are in second place in the Big 12.
Purdue is riding a seven-game winning streak following three straight losses.
West Virginia, Texas, New Mexico (MWC), Michigan State
West Virginia lost back-to-back games for the first time this season with losses to Villanova and Pitt. A win over either of those teams would have put them ahead of Purdue as a two seed.
Texas looked unstoppable on Saturday with a 91-51 win over Nebraska.
New Mexico is riding a nine-game winning streak. The Lobos have a half-game lead on BYU.
Michigan State ended a three-game losing streak with a win at Penn State.
Georgetown, Pitt, Vanderbilt, Wisconsin
Georgetown picked up their worst loss of the season on Sunday, losing at Rutgers.
Pitt has won three straight games. The Panthers beat West Virginia in three overtimes.
Vanderbilt has won two straight since losing to Georgia.
Wisconsin dropped into fifth place in the Big Ten. The Badgers should win at least three of their next four (@ Minnesota, Northwestern, @ Indiana, Iowa).
Xavier (A-10), Tennessee, Temple, Gonzaga (WCC)
Xavier picked up a huge OOC win at Florida.
Tennessee has lost two straight games.
Temple destroyed Rhode Island in a 78-56 win.
Gonzaga swept the season series against St. Mary's with a win last week. The Zags are now No. 13 in the AP Poll.
Texas A&M, Illinois, BYU, Wake Forest
Texas A&M lost a four-game winning streak in a 59-54 loss to Kansas. The Aggies are in third place in the Big 12.
Illinois had a five-game winning streak snapped by Ohio State. Illinois is now in fourth place in the Big Ten.
BYU responded to their loss at UNLV with a 91-48 win over Air Force. The Cougars are in second place in the MWC.
Wake Forest has won five straight games entering their game at Virginia Tech on Tuesday.
Northern Iowa (MVC), UNLV, Butler (Horizon), Baylor
Northern Iowa picked up their worst loss of the season at Bradley. Luckily for the Panthers, Wichita State has struggled, so they still have a three-game lead for first place. The Panthers' magic number for a conference championship is down to one.
UNLV has lost back-to-back games to New Mexico and San Diego State.
Butler is yet to lose in conference play, and it will most likely stay that way with easy matchups in their final two Horizon League games. The Bulldogs play Siena in BracketBusters on Saturday.
Baylor has won back-to-back games by two points. The Bears are in fourth place in the Big 12.
Cal (Pac-10), Maryland, Richmond, UTEP (C-USA)
Cal has won three straight games.
Maryland responded from their loss to Duke with an 85-66 win over Virginia.
Richmond has won six straight games.
UTEP has a 1.5-game lead on Memphis in C-USA.
Georgia Tech, Tulsa, Clemson, Virginia Tech
Georgia Tech has lost their last two games. The Yellow Jackets need to beat UNC on Tuesday.
Tulsa dropped into third place in C-USA with a loss to Memphis. The Golden Hurricane need to win at Marshall on Wednesday.
Clemson won their last two games.
Virginia Tech has won four straight games and plays Wake Forest tonight. A win over Wake would put the Hokies in second place in the ACC.
Ole Miss, Oklahoma State, Marquette, Rhode Island
Ole Miss has lost three of their last four. The Rebels play second-place Vanderbilt in their next game and then are in a position where they might be able to win out in the regular season, with their toughest games being at home against Florida and at Arkansas.
Oklahoma State ended a three-game losing streak with a 97-76 win over Oklahoma. The Cowboys need to win their next two games at Iowa State and at home against Baylor.
Marquette has won five straight games and has moved into sixth place in the Big East.
Rhode Island lost back-to-back games for the first time since January of 2009.
Florida State, Memphis, Louisville, Missouri
Florida State has games at Virginia and North Carolina coming up this week. The Seminoles need to win both.
Memphis moved into second place in C-USA with a win at Tulsa. Memphis has a fairly easy four-game stretch coming up (@ Tulane, Southern Methodist, @ Houston, Southern Miss).
Louisville picked up a signature win at Syracuse on Sunday.
Missouri lost a big game at Baylor 64-62. Missouri plays a tough game against Texas but then has a short, easy stretch with games against Nebraska and Colorado.
Siena (MAAC), Florida, UAB, Northeastern (CAA)
Siena lost their first game in the MAAC at Niagara. The Saints rebounded with a 74-57 win at Canisius on Sunday. Siena is in desperate need of a win at Butler in BracketBusters on Saturday. This game is scheduled at 11:00 AM EST on ESPN2.
Florida has lost their last two games and is now close to dropping out of the field. The Gators must win their next two games against Auburn and at Mississippi.
UAB has come close to dropping out of the field with losses in three of their last four games.
Northeastern lost 53-52 at William & Mary on Saturday. The Huskies have a lead in the tiebreaker for first place with Old Dominion.
Oakland (Summit), Charleston (SoCon), Murray State (OVC), Cornell (Ivy)
Oakland has a multi-game lead on IUPUI in the Summit. The Golden Grizzlies finish the season with three home games against South Dakota State, North Dakota State, and IPFW.
Charleston has a half-game lead on Wofford in the SoCon. The Cougars host Appalachian State on Wednesday and then finish the season on a three-game road trip with games at George Mason, Wofford, and Furman.
Murray State is tied for the nation's longest win streak (Butler) at 15. The Racers' magic number for an OVC championship is down to one. Murray State plays Morgan State in the BracketBusters.
Cornell was upset at Penn on Friday. This was only Penn's fourth win of the season. Cornell then struggled at Princeton but gutted out a 48-45 win.
Utah State (WAC), Weber State (Big Sky), Sam Houston State (Southland), Kent State (MAC)
Utah State is in sole possession of first place in the WAC. A loss for any of the 13 seeds or a win over Wichita State for the Aggies would allow Utah State to move up.
Weber State beat second-place Northern Colorado last week. This win gave the Wildcats a multi-game lead on Northern Colorado. Weber State's magic number for a Big Sky title is now two.
Sam Houston State has won their first 10 games in conference play.
Kent State lost to Buffalo last week. This dropped the Golden Flashes into a tie for first place with Akron, but they still have the lead in the tiebreaker.
Santa Barbara (Big West), Morgan State (MEAC), Arkansas State (Sun Belt), Robert Morris (NEC)
Santa Barbara holds a half-game lead on Pacific in the Big West. The Gauchos have already beaten Pacific twice this season.
Morgan State had an 11-game winning streak snapped by South Carolina State. This was Morgan State's first loss in the MEAC this season. The Bears have a three-game road trip coming up with tough games at Delaware State and Murray State in BracketBusters.
Arkansas State moved back into first place in the Sun Belt this weekend.
Robert Morris has continued to dominate the NEC. The Colonials host second place Quinnipiac on Feb. 20.
16 Seeds (Lehigh vs. Jackson State—Play-In Game)
Coastal Carolina (Big South), Stony Brook (Am. East), Belmont (A-Sun), Lehigh (Patriot), Jackson State (SWAC)
Coastal Carolina picked up their worst conference loss of the year at High Point. The Chanticleers still have a 1.5-game lead on Winthrop for first place.
Stony Brook has won seven straight games and has a half-game lead on Vermont. The Seawolves play Vermont on Feb. 24 in what could be a game for first place.
Belmont has won five straight games to take a first-place lead in the Atlantic Sun. The Bruins have a fairly easy finish to the season, playing the three bottom teams in the conference their final four games.
Lehigh has a one-game lead in the Patriot League. The Mountain Hawks have to play at second-place Lafayette on Feb. 21.
Jackson State holds a two-game lead on Arkansas-Pine Bluff in the SWAC. The Tigers' magic number for a regular season conference title is down to three.
