BASF,
Are you legit arguing that because Wilson played a certain way in college - this somehow clearly makes the case that Carroll is not the driver of this ridiculous 'explosive plays' focus or that it indicates Wilson is unable to produce outside of that box?
Lets review:
Carroll and his team are scouting for players that fit their preferences in play. Carroll has already demonstrated a predilection towards explosive plays. He finds a play that is exceptional at same...and shocking drafts him.
As explosive plays are a focus, per Carroll's own words, it is likely that a good percentage of practice time is used perfecting them. Probably not a crazy coincidence that Wilson got very good at that kind of play - as did his receivers.
(we know they devote a good % to scramble/breakdown plays)
Did Wilson fail to develop in those other areas because of the above focus? Likely. Is that an indication that he was incapable? 2015/2016 seems to argue otherwise (not sure the year he played injured).
10 years of playing a certain way will be difficult for Wilson to overcome. Perhaps almost impossible. But to argue Carroll couldn't be the genesis of the problem because Wilson played a certain way in college seems to ignore a lot of how scouting, practice, and player development works.
Wilson is full of himself, likely a piece of work. No argument. And it is easy to dislike him because of that and want to blame him. But this was all Carroll just trying to figure out how to make it work with such a flawed QB? Unlikely.
That last part of what you wrote where you question Carrols role in masking Russ's flaws... what Carroll did with Russ is exactly what the Broncos are going to have to do for him.
Carroll is famous for finding players that don't fit a certain metric, and installing them into a complimentary style of play that masks their weaknesses and amplifies their strengths. ITS literally, outside of the compete mantra, what he and this franchise are known for. So to look at Russ and think Carrol would do otherwise or that his ability to maximize a players attributes isn't a major factor... what Russel did well was just enough of what Pete needed that for years, he was able to build a winner around him.
Russ is who he has always been. PC said - I can work with what you do well... we can win with what you can do well. Don't turn the ball over, use your elusiveness and we will run the ball to help you and get you as many chances as possible with our defense.
When we couldn't or wouldn't run, and the defense couldn't get the ball back to an offense that was NEVER good at sustaining drives through the air... welcome to the 2017 - 2021 Hawks.
Russ had 3 coordinators to help him become a better xs and os QB. Each time one was brought in, it was to open up the offense. Schotty produced as much as he could with him... until Russ couldn't solve the looks he was seeing.
Waldron had the playbook, and Russ flat ignored it and did the same thing he always did.
Pete worked with Russ. So did every coordinator tasked with elevating the passing game. Russ just didn't develop.
