What I saw was a direct flashback to most of the flawed non-adjustment made, failures in Kelly's past.
He 'knew it all' before the game started and stuck with it as long as he could, even though it wasn't working and we were on the brink of defeat at the hands of a far inferior team. Only at the end, when he started mixing things up again did our offense finally get going and took the lead.
He already 'knows it all' of what we need to do against Navy, but unless they just play terrible it isn't going to work well and Navy will stay in the game, won't matter because he knows best and he'll stick to his guns until late in the game, then switch to what we really should have been doing the whole game to pull out a closer than it should have been win.
The way Kelly coaches keeps lesser teams in games, giving them chances at stealing Ws that never should have been there... we've seen it time and time again for 9 years now, he's not going to change.
