Greg Oden, whose had three microfracture knee surgeries in his young career, is attempting a comeback. He's been taking his time rehabbing so he can make his return next year. Multiple teams are interested, including the Heat, who need a big body in the worst way. Oden won't be ready until the fall, but a team like Miami can afford to take a gamble on the former No. 1 pick and see what he's got in time for the 2014 season.
