Our four rookies are averaging :
Rudy: 26.5 MPG for 40 games
Oden: 22.7 MPG for 35 games
Batum: 17.6 MPG for 41 games
Bayless: 11.4 MPG for 21 games
It's not like these guys are all playing 35 - 40 minutes per night. Rudy and Batum were both starters who played heavy minutes for their European teams. Granted, the schedule was shorter, but they are both used to playing more MPG than they are currently getting.
The more Oden plays, the better shape he's in. He's finally starting to get into game shape where he can play more than 24 minutes without kealing over. Unless Nate starts playing him 40 minutes per game, I don't see him hitting the so-called rookie wall anytime soon. In fact, I see him continuing to improve as the season progresses.
And Bayless played over 4x as many minutes last season in colleg than what he's played sor far this season in the NBA.
Given their roles and their PT, I don't expect our rookies to hit any kind of "wall". If anything, I see them continuing to improve (especially Oden and Bayless) with more PT and more experience.
