Good point.Let's keep in mind when bringing up the 4k yards that all we did last year was throw the ball. Not to discount Tanney but it is a fact that we would totally disregard the run game for weeks at a time.
But, let's also not forget that it is much harder throwing against 6 or 7 guys while the defense generates a lot of pressure with only 4 guys. And, without the threat of a run game to take them out of coverage, he cannot use one of his best tools, the play action fake. Also, the DL can pin their ears back and give a full rush every play.
I'm confident that any QB would prefer to have a running game. Heck, even the fantastically successful passing game of Green Bay that we were modeled after does. The great Aaron Rodgers was ecstatic whenever he had a running game.
Yes, throwing all the time will rack up higher yardage totals. That is very true. But, when they know you can only pass, it gets much more difficult to pass. Especially when your OL is imploding for one of the top 10 ever worst sacks years in NFL history.
Even when throwing all the time, those are some impressive numbers when you can't run.
