I think you should rename this thread "F you, Andy Reid."
Correct me if I'm wrong, but I don't think it's Westbrook responsibility to report to the league he's sitting out. Westy is a gamer, and probably wanted to play but my money is on it being Reid's decision to scratch Westy. I'm guessing his reasoning was to give Brian some time to rest while the other guys beat up on the lowly fudge Packers.
I have Westbrook in one PPR keeper league. I've owned him for three years now and have gotten used to the fact that he is a big time injury risk. It didn't burn me this week, as I already had the win wrapped up going into Monday night's game. However, that risk involved, IMO, is worth it considering how money he is when he plays.
