I really don't understand how some of you come to your conclusions. Like you can't be watching the games or pouring over stat sheets. Every reason you mention why Powe should NOT get the minutes can be just as easily applied to PJ, if not more so.
PJ was HORRIBLE in game 3. He was playing in place of Perk to defend Gasol, who Perk was absolutely owning. While giving us nothing on the offensive end, he blew 2 or 3 defensive plays in a row. On a nice defensive stand, the Cs forced Fisher into a bad spot, he almost knocked it out of bounds and had to save it. PJ was in bad position and let Gasol get into a clean passing lane, so naturally he has to yank him from behind and send Gasol to the line with 2 on the shot clock.
Next possession he gets away with a clear foul when he mauls Gasol 16 feet from the hoop late in the shot clock.
We have to be honest about PJ here: Hes' NOT A 20 MINUTE PER GAME GUY. Yes, he played great in game 1 and pretty solid in game 2. He also was terrible the entire Detroit series. He's old, he's slow, he's an offensive zero, he isn't as effective as he was 2-3 years ago. He should never play over Perk late in the game. Ever.
