I haven't checked the stats on this, but it looks to me like MDA is playing 10 in the first half, and then tightening things up in the second half. I thing that's very smart for a number of reasons:
* We get to see what we've got -- gives us a chance to evaluate whether Walker, Moz, AR, Mason are good enough to be in the long-term rotation
* Keeps minutes reasonable in 1st 1/2 for everyone so we can go with whoever's getting in done when it's winning time
* Gets enough guys into the game's rhythm so we don't have to be rigid about giving 2nd half playing time to particular guys -- can play the hot hand
* Keeps cumulative minutes reasonable for our top players; hopefully this will help keep them healthy and fresh throughout the season
