Duncan/Bonner/Mahinmi
Oberto/Thomas

Surprisingly, I'm very optimistic about this lineup. Obviously we will see Duncan and Oberto/Thomas in the starting lineup (I suspect we'll see both throughout the year, with Oberto starting opening night), but this also means we'll see solid minutes for Bonner and/or Mahinmi. Here's how I see it breaking down during the regular season:

(There are 96 minutes per game to distribute; for the sake of simplicity, let's distribute 90 minutes, assuming Pop goes to Udoka or Gist at the small ball 4 for an average of 6 minutes a game.)

Duncan - 34 minutes per game
Oberto - 19 mpg
Thomas -19 mpg
Bonner/Mahinmi - 18 mpg

I personally think Oberto/Thomas is the best "two-headed center" we've had since we started using the concept after Robinson's retirement, but I'm also excited about Bonner and Mahinmi getting a chance to prove themselves on the court. I've always been someone who felt that Bonner can be a solid contributor for this team if given decent minutes, and I also feel that Mahinmi needs to be thrown into the fire a bit early in the season.

Obviously many of you are not as optimistic about Bonner as I am, and if Pop agrees with you he will either be benched or traded. How does everyone else see the rotation working out?
