<div class='quotetop'>QUOTE </div><div class='quotemain'>To give you a picture of Collins's awfulness, the league average in PER is set at 15.0, and usually only scrubs or defensive specialists fall below 10.0. Collins's rating? 0.9</div> here I cried
<div class='quotetop'>QUOTE </div><div class='quotemain'>Not that Frank had many other options. Unbelievably, three of the league's four worst PERs belong to the Nets' frontcourt players. Jamaal Magloire, at 2.21, was third from the bottom (I guess $4 million doesn't buy what it used to). And the hobbled Nenad Krstic, at 2.23, was fourth, though at least he has an excuse.</div> I still think the PER is a sham, but this made me cringe.
PER is very overrated. It only accounts for offense and puts too much emphasis on scoring. Now, I do think Collins isn't a starter in this league but he could be a great bench player.
