EASILY Thabeet, he was #2 and multiple All-Stars were picked after him, and the fact that he is no longer in the league. Robinson was a lottery pick, in what was considered a "weak" draft; but at least Robinson brings something to the table (as already mentioned) in athleticism, hustle, and rebounding.
Is he really? Coming out wasn't he touted to be the best high impact player in his class? If he was all that, athletic and a good rebounder I would have thought he would have stayed around. IMHO Robinson is suffering from Lin-itis and keeps thinking it is the lack of opportunity rather than the lack of skills that is preventing him from succeeding in the NBA. Maybe it's showing in his stubborness or lack of drive/hard work in workouts because unless people think you're hopeless they won't keep throwing you around, he was a former top pick for crying out loud.
