No, I don't think Pierce is the problem. I saw this thread earlier, but after randomly browsing the internet and running across Hoopshype.com, there is an article on there about Durant being an offensive machine.
Well our Captain matched Offensive Machine Durant nearly Point for Point in the game in OKC just a couple of months ago...at least until KG went mad and took over in that amazing 3rd quarter.
Pierce still has it..yes he is a little older, a little banged up, a half-step slower or so..but the man has it, and still demands much attention from our opponents every night.
I cannot answer why his last few games have been less than stellar - maybe multiple defenders? Nagging Injury?
If it is a Nagging Injury, then knowing Pierce he will play through it, even if it throws his game off some. That's what makes him a Great Player, but sadly a flawed one (in that he still plays with an injury) I think...If it is an injury, I certainly wouldn't mind him resting some more...
If it's the defensive schemes of our opponents, then it's Rondo's job I would say to correct for that.
We only have five weeks left in this regular season, and I think we can still pull off 50-55 wins.
