Don't go over the edge here... Lee's been fantastic this season but struggles against a couple types of players. In fact these days, I don't think there is a truly dominant PF out there. They all have their respective Achilles'.. Z-Bo can struggle with lengthy players that can't be easily forced off the block.
Duncan has trouble with quick/smart PFs
Blake has a problem with crafty smart PFs
Aldridge has a problem with PFs that can guard jumpshots really well
Just saying, we have a really good PF, and I don't think he's the problem here.
