I'm leaning Robinson since he has access to playing time, where Bamba is stuck behind Vuc as long as Orlando keeps winning...

I battled with this debate in a couple places this year where I owned both of them and had to choose one or the other, especially since for most the season their stats have been near identical, but in the end I went Mitch Rob. If he can figure out how not to foul out in 7 minutes, he has all the opportunity he can handle - it's all up to him. Bamba doesn't have that luxury. I really wanted it to happen for him - that 3.7 blocks/game in college was tantalizaing, but unless there's a trade, Vooch gets hurt, or the Magic fall out of the playoff race, I don't think Bamba will be worth owning in most standard leagues this year.
