At first glance, Blatche seems like a no-brainer for the All-Breakout squad. He made a sharp improvement last season, he's only 22, and the incumbent starter at his position was just declared out for the season. Unfortunately, that pesky six-foul rule may prove to be his undoing. Blatche averaged 6.02 fouls per 40 minutes; with a rate that high and the current ultraconservatism that coaches use with foul trouble, it will be extremely difficult for him to average more than 25 minutes a game.

乍一看，布雷彻在这个阵容中就像个打球不用头脑的人上个赛季，他有很大的进步，而他只有22岁，球队刚刚宣布他是这个赛季的那个位置上的首发，不幸的是，六次犯满的规则可能让他毫无作为，因为每40分钟他有6.02次的犯规，犯规的频率很高，而球队的教练是个极端保守的人人，对于犯规麻烦更是苛责，对于布雷彻而言，每场上场超过25分钟是一个极为困难的事情。
