Can Yi play at the NBA level? That's a good question

Every player in the draft has a certain risk-reward quotient.

Greg Oden's risk factor went up a point or two this week when word trickled in that his physical from the predraft camp in Orlando was red-flagged with concerns about the long-term health of his wrist and a bulging disk in his back. This could certainly give Portland pause before drafting him No. 1.

Meanwhile, Kevin Durant caused an uproar several weeks ago when he tested as the worst athlete in the draft. No one believes Durant is a bad athlete, but the test results raised questions about his preparation for the draft.
