Wow, how did u get Tyreke, Westbrook, Lopez and Dwight. That's a pretty nasty 4-some. Your percentages might be hurting a bit with Westbrook and Ariza dragging down fg and dwight dragging ft, but overall - that's a decent team. You should check out this website for really good, in depth fantasy analysis. http://bit.ly/bviij8
