Having two improved things, overall qb play and just a better passing game, which includes just more experienced and higher abilities is doing many things.
We all see the obvious, over the top dimes, wrs running dbs off the ball with a perfectly timed ball coming in etc. But imo, whats happening is, our dbs are getting roughed up a little. Just because our offense can now actually do that. Iron sharpens Iron. We didn't do well on 3rd down D last year, and it wasn't competition running over us, it was them passing over us. Imo, we will be much more prepared, skilled and successful this year.
So real competition is going on, the ultimate complimentary football.
