While I agree all teams have injuries, not all injuries are the same and they don’t impact all teams equally. Losing McCoy hurts a lot more than losing say Young. If you don't have depth at the position of injury, things get a lot more difficult in a hurry. Injuries matter, and hurts some teams more than others.
We simply don't have the depth of KC or Buffalo or a number of other teams. It is what it is. With McCoy, we averaged 40+ ppg, without him and partially without Hill, it's been half that. I think some people are underestimating just how devastating the loss of McCoy was. And Hill hurts a ton too.
