GM Bryan Colangelo admitted Thursday he has some concerns about Kyle Lowry's health and expects to acquire a backup point guard by the Feb. 21 trade deadline. Lowry has dealt with back, triceps and ankle injuries this season, so the Raptors have reason to be concerned. After trading Jose Calderon on Wednesday, the Raptors' depth at the position is certainly in doubt. John Lucas scored 19 points, including three 3-pointers, to go along with two assists Wednesday, and it'll be up to him to prove the Raptors don't need to add another PG. As for Lowry, as long he's healthy, he's an absolute must-own with Rudy Gay coming to town and the starting job all his.
