Paul's photo: In an effort to keep the Spirit of Mark Blount on the team, they replaced Pierce's hand's with Blount's. In that spirit he kept up Blount's favorite ratio of not having more rebounds than turnovers.
Cassell's pic: I've heard of rookie hazing, but picking on the old veteran like this is just not right. As Racker pointed out though, he did extend the common courtesy.
Powe's pic: I've got to give Doc credit for once. I don't think KG actually had a child. I think Doc just locked him in a padded room and didn't feed him. That is the only way to explain this kind of intensity and literal hunger for Powe's ear (Truthfully, I wish that I had half of that intensity while I worked).
