I have a completely speculative opinion about GT. GT was pretty good but needed a little time to get the rookie skill positions [other than the excellent QB] in full flowing synchronization with the spontaneity aspects of the Johnson system.
Then along comes Bobby Elliot with his weeks long scouted scheme to stop them. And we stuff them [other than the two gimme off-pattern passes to the fullback very late in the game.] Elliot's "film" gives everybody else the method to ruin the GT offense --- plus, and I think that this is underrated on IE, playing ND is no treat, and we beat up our opponents for four quarters no matter whether we fans see that clearly or not.
Result: GT is really up against it for three weeks before Johnson and his team can adjust and begin to feel good about themselves.
I wouldn't be surprised if they're very threatening from here on out.
