Here is what I'll say about the Jalen Hurts article. He has had 2 competent offensive coordinators in his career. Both left for head coaching positions after Super Bowl seasons.
He has also had 2 incompetent offensive coordinators in his career. Both were first-time NFL playcallers, both went 1 and done, and neither is even a position coach now.
Hurts has limitations. He has preferences. Every QB does. A good OC works with his QB and meets in the middle to find what works for everyone. Two guys did that. Two guys didn't. The results speak for themselves.
If you want to use those preferences to argue that the son of a coach, who also played for Nick Saban, isn't coachable, that's where you lose me.
The article even acknowledges that both Moore and Steichen came in with a plan about how the offense would function, while lines were more blurred with Johnson and Patullo.
I fully expect Mannion to come in with a plan as well and push back on Hurts' preferences when necessary. He doesn't have the clout of being a longtime coach or an experienced playcaller, which does make it a bit of a dice roll.
But Hurts has a relentless work ethic, and after the way last season ended, I'd expect him to be more open to change, especially if it is coming from someone competent.
