Let me ask the people who claim that injuries shouldn't affect expectations. So...you are saying that there is absolutely no level of injuries on a team that could prevent the coach from winning a championship?
What level of injuries are acceptable? Zero, one, two? How many before we should start lining up the excuses and lowering expectations? Florida State loses Winston and I can see tempering the repeat expectations - but I bet that fan base would still be planning trips for the playoffs. Rose + Jackson < Winston (by a long shot). Our expectations have always been B1G championship. That isn't going to be lowered by the loss of a couple 2nd stringers and the 4th best RB.
There are injuries every season, for every team. We're going to have more than this, I will 100% guarantee it.
So why does everyone jump off a ledge when they start to occur - packing it in looking to 2015 (where we'll again have injuries)? There are a lot of uncertainties in football. The coaching staff is paid 6 million a year to adapt to the changing landscape. We have 120+ kids on the roster so we can make those adjustments and find the best 22. If an injury or two sinks a season where we've already built in a couple losses as a best case scenario - 3 weeks before the first game - then the 120+ isn't adequate, or the staffs' ability to adjust isn't adequate.
