Why would they be pi$$ed off at all? Injuries are part of the game and are pretty much expected. That's why it is commonly said, especially among GM's and coaches, that the NFL is a 100% injury league. They know every player will at some point miss time due to injury. A few unreasonable fans are the only ones who get pi$$ed at players because of injuries. One would think most fans are knowledgeable enough to know better.
