It is true. In general you do want a run/pass balance on offense. Every team strives for this. When the team gets on top, generally they run the ball to control the clock. The passing game gave us a big lead 14-0. And for once it wasn't the bombs away passing attack. It was the quick slant/ drag/ hitch/ screen/ short passing attack. We have 3 players in Brown, Eli, and Ayres that can get good YAC on these types of passes.
Once the Steelers had a big lead, they went to the run. And if they can't stop it, you stay in the run. All ****** day! It's what college teams do. At least the teams that win a lot. That 3rd drive that was all Bell, was a perfect example. The next time it was run heavy as well. You run-run-run until they can stop it. Miami couldn't. That is when balance doesn't matter, you go with what works. The rest of the game should have been strictly a run run run game the entire second half. Maybe call a screen or quick pass play, but you don't want your QB to take a hit.
I'm disappointed that they didn't go back to the quick passing attack that worked, when the lead was even bigger. It became the ol' chuck and duck offense of ben trying to get 15-25 yards each play. That is the moment, as a head coach, where you have to take out your starting QB to protect him against himself.
