I think I see where a distinction needs to be made: A lot on this forum are hesitant to blame Chinander for poor play because of the dynamic of Year 1 changes and all of that. To an extent that is perfectly fair. Where I blame Chinander is for scheme issues that he is directly responsible for.
A lot of these go hand in hand. Injuries played their part, too. You can only do what your players are capable of doing, and with the transition the number of guys capable of executing any particular call wasn’t always where Chins wanted. For instance, he wanted to play a lot more man coverage, which would have allowed him to be far more aggressive up front.
Sometimes there are bad decisions that can be corrected. One I pointed out at the time last year was the decision to come out in 2 high versus Illinois. No reason to against that passing attack and that decision often left us minus 2 in the box. This was corrected in game.
