I came to look at Russ / Hawks as a high-wire act. No other, or few other QB's could do what Russ did, which was essentially back-yard football...shitty line, questionable scheme, run-happy HC. He was so athletic, and had athletic receivers, he was able to pull the rabbit out of the hat for a long tim, with a great defense to keep him in games until he could "cook".
IMO, this played into the "We need a great line for Russ" narrative. The more I watched him (them), I came to believe that the shit-tier line allowed him to do his back yard stuff, with great effectiveness, and Pete / Schneid got that. Put him in the pocket behind a good line, he would have been fringy-out of the league in 3 years, which is why he "fell" to them in the 3rd round.
Defenses would stack the box for 3 quarters, and then Russ would go Fran Tarkenton on their ass and pull it out at the end, which worked with an "elite" defense, last several years, not so much...
It was highly entertaining to watch when it was good, and painful when it wasn't. They adjusted with the 'Rainbow" ($75k) deep passing game, but it ran out of gas after a while...
When every time you win, 4-5 circus catches are in the highlights, it isn't sustainable...
