By showing his stats (especially mpg) compared to Mahinmi I was hoping people would see that he was already playing at least to Mahinmi's level in Cleveland. And that's all we're really looking for out of him (though I'd love to see Roy's minutes decrease some). He gives us a needed, capable third center (whether he's #2 or #3). Anything more we get is gravy. He's not going to be a guy like Fez that gets us excited but never gets on the floor (well, unless he has an attitude implosion). And my expectation is that he'll have a significant impact on the second unit offense. He's someone that the opposing defense will have to work to stop which should open up opportunities for the other players (as Quinn said the other night).
The Pacers have suggested that Bynum will move past Mahinmi in the rotation. Will he? I don't know, but I hope he does. And I think the Pacers have to say that and set that goal to motivate him. They need him to come in and work hard to fit in with the team. If he thinks he's coming in to sit on the bench until an emergency then I doubt he puts in the work he needs. So now we just wait and see what happens in practice and how he (and Mahinmi) responds to the competition.
