Chip Kelly is/was an "offensive genius", Tom Herman is not. He is not even in the same stratosphere as other "offensive geniuses", IMO. Herman lost my confidence against Northwestern last year when I watched him (and it wasn't the first time by any means), as he calls it, "Fall into old bad habits." From there I kept quiet and gave him the benefit of the doubt because he was winning games. Now it seems that Braxton and Carlos helped to hide many of his inadequacies. He has shown no real ability to make necessary in game adjustments and I think a team with this much speed and talent deserves better. He seems to show up with a game plan (in most cases not a great one) and he runs it into the ground regardless of it's rate of success or failure. The few adjustment he does make are generally overdone and make us predictable.
I don't hate the guy, but I'm def not on the side of things where I am fearful he will take a job elsewhere. I actually hope he does so that things organically take care of themself.
