The lockout kept him here. He was a first rounder after his freshman year. I understand you want to see him as this altruistic guy who stayed because he loved it, but without the lockout he's gone. Things have changed since then though. The NBA isn't as concerned with proven talent anymore. They draft based on measurables and potential. That's the only reason Bradley was picked in the first round last year.
I agree. As much as I would like to see Little back next year, I think he's gone for the reasons you mentioned. The NBA draft now is all about potential, and in a weird way, staying actually hurts a player's chances of getting drafted high.
