The stocky point guard out of Villanova has seen his fair share of ups and downs throughout his seven-year career so far.
As a member of the Houston Rockets last season, he suffered a bacterial infection which sidelined him for nearly 20 games. During that stretch, his backup Goran Dragic broke out into the scene and established himself as an exemplary point guard, and eventually ended up starting the rest of the season.
This is familiar territory for Lowry, as he seems to have lost his starting role once again, after Calderon played an exceptional stretch of games. He went down earlier this season due to a tear in his tricep muscles, per Marc J. Spears of Yahoo! Sports.
If the Celtics do end up pulling the trigger on a few trades before the deadline, Lowry will unquestionably be the starting point guard for the club.
He has only two years left on his reasonably paid contract, so he won't severely cripple the Celtics' hopes of bringing in other quality players in the future.
Besides the fact that the Celtics don't have a real point guard on their roster, Lowry is perfectly capable of holding his own against the elite point guards in the NBA.
In 31 games this season, he's registering per-36 minute averages of 17.7 PPG, 7.6 APG, 5.8 RPG and 1.7 steals with an astounding 21.3 PER (per Basketball Reference).
Those are clearly All-Star caliber numbers, so acquiring Lowry would be a terrific investment for an old Celtics team looking to make one last push in the playoffs.
