one of our best offseason moves
I also give a lot of credit to the coaching. Not just the teaching part, but the refusal to play favorites--remember during training camp Nesbitt was told that if he played well enough to win the job it was his. (Okay, I'm typing this and it seems obvious, but that's not what we had in the past.) Teaching, no favorites, and being held accountable has inspired this line to make the most of their abilities and has molded them into a unit.
Having a qb who gets rid of the ball quickly and a coach who gives the o-line some help by designing and running plays that take advantage of the qb's ability to make quick decisions is also a big factor.
