You should try watching a few games before you post out of your ***. The only time Haywood plays well is when Kyrie is out. When the team is at full strength, Haywood is an afterthought who hides in the corner and watches the rest of the team play basketball. Even when he does get open, half of his teammates won't pass him the ball because they don't like him, either.
Try watching his body language, even when they win. He clearly isn't happy in his situation and doesn't fit in with his teammates. Can't really blame them after Haywood admitted he was rooting for them to fail when he was injured.
The Celtica aren't winning anything this year, but even if they did, Haywood will be the guy walking to the locker room by himself while the rest of his teammates celebrate with each other. Dude is one sorry son of a bitch and he has nobody to blame but himself.
