I hate injuries as much as the next man, but it's a part of the game. IRL, players contract serious injuries and are out for months or even the whole season. It might not be fun, however, that's a portion of the realism in BB, and I wouldn't want to see it being changed.
I agree with the Big Dogs. Injuries are a necessary component of the game. Like many have posted, I also am seeing more injuries in both my primary and Utopia teams this season than ever before, and so I understand the frustration, but I also enjoy the variability and surprises that come with having to adapt to these new circumstances.
