This is an interesting post because he got to spend some time with the coaches at some events they had with ex players, and has some actual details.
It's not surprising, but as suspected Kelly will not be running his college offense. Rather, he is going to run a hybrid of the read option and west coast offense. It's going to emphasize not turning the ball over at QB. And it's going to emphasize running the rock--a lot.
On defense, they are going to run a hybrid as well, featuring standard 3-4 and 4-3 looks as well as a 4-3 under.
In short, Chip is going to keep people guessing. The anti-Reid.
The big message Gcobb seemed to take away is that they want to be a more physical team. Music to my ears...
