2. Scott Tolzien, Quarterbacks Coach, Dallas Cowboys
You probably haven't seen this name thrown out there for offensive coordinator consideration just yet, but Scott Tolzien should definitely be getting some attention in the near future. For the past three years, he's served as the Cowboys' quarterbacks coach.
You can credit Tolzien for those games Dallas has survived over the last couple of seasons without Dak Prescott. Dallas was still finding ways to win games, at times, without Dak, and Tolzien should get some of the credit there. A guy like Cooper Rush should have no business winning football games, but Dallas somehow managed to do so with him under center.
Tolzien, a former NFL quarterback, didn't exactly pan out as a pro. His career spanned between 2011 and 2017, although mostly as a backup or practice squad player. Still, many of these types of quarterbacks have gone on to become good coaches. It's almost as if their inability as a player has made them better from a coaching standpoint. The knowledge is there.
If Pittsburgh wants to hire someone from a top-5 offense, Tolzien should get some consideration.
