For graduating seniors looking to find a home with an NFL team, the Senior Bowl is a late opportunity to showcase skills in a game situation prior to the countless combines and interviews they'll each endure in the weeks leading up to April's NFL draft.
In an all-star game such as the Senior Bowl, scouts know that not everyone will have their best day, but by that same token, a miserable performance can certainly damage a player's draft stock, at least in the eyes of some scouts.
While there were many who performed well enough to all but cement their chances at being high-round picks, a handful of collegiate stars were duds in Mobile, Ala., and it could cost them come April.
Here's a look at some of the players who disappointed at the 2013 Senior Bowl.
As one of the top quarterbacks in the draft pool, Ryan Nassib had an opportunity to raise his stock on Saturday night, especially after his former coach at Syracuse, Doug Marrone, was named as the next head coach of the Buffalo Bills.
But Nassib struggled consistently after entering the game in the first half, and threw for just 44 yards on 4-of-10 passing for the North team.
More importantly, Nassib was picked off once and fumbled the football after being sacked in the third quarter, so for a quarterback who threw just 10 picks in 2012, it was an uncharacteristically bad night.
After his storied four-year career with the Oklahoma Sooners, Landry Jones figures to be among the first 10 quarterbacks selected at the draft, but his performance at the Senior Bowl won't be doing him any favors.
That's because Jones was likely the worst of the six quarterbacks on the field. He completed just three of nine passes for 16 yards, and was shown up by fellow South quarterbacks E.J. Manuel and Tyler Wilson.
Maybe it's because Jones didn't want to risk throwing a pick, as turnovers plagued him consistently during his senior season.
As CBS Sports' sixth-ranked free safety, T.J. McDonald will be taken within the first five rounds of the draft, but the former USC standout wasn't at his best during the Senior Bowl.
His play wasn't nearly as noticeably bad as Jones or Nassib, but McDonald was caught out of position badly at one key moment, as Michael Williams, Alabama's behemoth of a tight end, found daylight and Manuel hit him for a 20-yard touchdown.
McDonald won't be hurt much by his play at the Senior Bowl, but especially against a tight end, he's expected to be able to handle a deep ball like this one more effectively.
