I'm chalking up last year (without Grubb) to the type of QB we had. Though I really never like dumping the blame soley on one player when so many other coaches and players are involved. But I don't see Grubb, especially if he has success, being with DeBoer forever. I'd love to see DeBoer call a game himself just to see what he'd do. There have been a lot of coaches who've done that.
I hope you're right and it is like McCartney and Lennon and not Brooks N Dunn. Who together, was hall of fame worthy, but separate, just so so.
