FBM,

To be honest, I just don't know.

I'm guessing he will be eligible for this year's draft, but if so, he also would have been eligible for last year's draft due to his age. It seems odd that he could have been drafted (again) after already playing pro ball and before ever appearing in a college game.

Technically all draft eligible players that are not drafted become free agents until they attend class for the following year. the August signing deadline.
