What did the Steelers have in those 2 decades between Bradshaw and Ben? Teams with a knack for identifying talent or coaching up QBs wouldn't take that long.
Mayfield was also better with the Browns than Fields has been with the Steelers in his first 2 games.
Please, Cowher for the majority of his coaching career DE-emphasized QB being the feature of the offense. Run the ball, control the clock, win with a stifling defense and getting turnovers was his mantra. He was a Schottenheimer pupil. Do you even remember “Marty Ball? He was very successful with that MO. In fact most teams without a franchise QB were and are successful following that method. Stewart and Chan Gailey allowed Cowher more offensive opportunities. When Gailey left, it wasn’t until Mike Mularkey and Whisenhunt with Stewart, Bettis, and Hines when pick your poison play calling really balanced Cowher’s game plan. But still, he followed run to set up the pass philosophy, even when Maddox took over with the Tommy Gun spread offense, once he achieved a lead he would sit on the ball and chew up clock.
Hell, when Ben replaced Maddox, Cowher practically told Whiz to put a leash on him because his backyard ball tendencies which went against his philosophy of ball control. Fortunately, he slowly allowed more slack on play calls for Ben and that SB run as a last seed really showed Ben as a franchise type QB. Still, Cowher followed his mantra till his retirement, play great defense, get the lead and use up the clock.
Now when Goodell came into the league and adjusted the rules, again, for offenses to score more points the game changed from the 90s - early 2000s. Tomlin had a franchise QB, he didn’t need to change anything until Arians (and Ben’s) offense started to get Ben killed. They brought Haley in who did what Whiz did and helped return the prolific balanced offense to complement the awesome defense. Cowher had 3 QBs, Stewart, Maddox and Ben to put him over the hump into Conference champion games. All those other starting QBs…….Bubby, NOD, Tomzack, were game managers. Which life after Ben will probably be what we see what Fields can do. With a decent OC who knows, but until another Ben falls in our lap, the game manager, which is what 75% of all starting QBs are in the league. So, Tomlin will do what Cowher did…..Marty Ball, with a dash of explosiveness on offense.
