He put it well himself.
It is similar but he is more from the school of Tom Moore, then Joe Gibbs (like Whiz was).
The roster turnover won't be as drastic as if a Mike McCoy came in with a new passing system, and new running scheme.
The biggest disappointment EVER, was when Whiz came to the desert and I thought, "FINALLY, smash mouth football." and it never came. If never came close. They could never run the ball, and passed all the time....just never liked that. Ever.
With Arians, (talk about setting myself up again) I would expect for the ball to be thrown all over the place. I would be surprised to see a running back taken before the 3rd round while he is hear, and if he has the control to do that.
Don't think of Whiz when thinking of Arians, think of Tom Moore from Indy and the offense they ran with Peyton, and later Andrew Luck.
Makes sense why he was snatched up by the Colts.
We will see, but those are my predictions based on what I think.
