what makes you think that kelly is trapped/locked into that read option stuff and that he wouldn't adapt?
he's already said he would and those who have worked with him said that he adapts what he does to the personnel he has.
i've said it before, the problem with chud was that he tried locking newton and the offense into some new creative mold where he should have just used an adaptable offense like he did last year...which is what kelly does.
he will have his own slant on things that will be different than most coaches in the league, but i can promise you that it won't be the exact same thing he does in oregon. the no huddle hurry up offense will probably be there as will his aggressive game management and it will be a spread of some kind, but it won't be the same thing.
he diagnoses what defenses does and then changes his play calling to take advantage of weaknesses they present and he allows the QB to make those calls on the line regularly.
chud was just to inflexible in what he was doing and was unwilling to deviate from his original plan. it wasn't the scheme that was the problem. it was the play-calling and game management.
Wait.. he complimented John Fox on adjusting to player personnel?!?!? Next please. I kid I kid
