I guess, one question that would have to be answered, is Bradley/Allen/Pietrus a legitimate back court unit?
I'd imagine if Bradley were to continue to start, Ray would come in for him around 6 min mark. Allen and Rondo finsh out the 1st qtr, with Pietrus coming in for Pierce around the 10 min mark.
Starting the 2nd qtr, we'd have Bradley, Allen, & Pietrus. Pierce would come back around 8 min mark (for Allen) leaving Bradley, Pietrus, Pierce. Rondo comes back at the 6 min mark leaving Rondo, Bradley/Pietrus (whichever is playing better), & Pierce. Allen could then finsh the qtr, coming back around the 4 min mark.
This leaves a minutes break-down of (per half):
Pierce-18 min
Bradley-12/14 min
Rondo-18 min
Pietrus-8/10 min
Allen-14 min
