I know well enough not to suggest it, but if anything I'd like to see more and greater injuries, as at its current level we are farrrr below the NFL injury average. You're complaining over one player on IR, whereas the Giants last season ended the year with 20 players on IR, at least 6 of whom were starters at the beginning of the season. Total, they lost 91 starter games due to injury. No team finished with less than 4 players on IR in 2014, and the Jets led the league with only 20 starter games lost during the year.
Injuries are one of those tricky things to implement into a football sim, because they're inherently negative. No one enjoys when it happens to them, even if they'd be oddly unhappy if it weren't a part of the game at all. So it's always a balance to have it 'be there' without feeling overwhelmingly onerous.
