How did it work out?
I'm talking about risk mitigation, not handcuffing. Tua got hurt on a passing play. This might have cost Alabama the LSU game because he wasn't healthy. Then, Tua got out for the season on a passing play where he was trying to do too much when Alabama already had the game well in hand. Then of course there's the passing play three yards from the end zone that cost the team the Auburn game and a shot at a championship.
Every time you let the quarterback keep the ball in his hands you are dramatically increasing the odds he gets injured and you are dramatically increasing the odds that the team turns the ball over. This isn't opinion, it's statistical fact. That doesn't mean you don't ever do that, you do need a balanced offense, but you mitigate the risk by having a strong running game so you're not forced into doing that, or that it doesn't become habitual. Tua got injured for the season on a routine play, but a routine play that never should have happened. He shouldn't have had the ball in his hands on the sideline in those circumstances, period but it was ingrained behavior.
As far as the other stuff, keeping people happy and what have you, a balanced offense that protects the ball and protects the QB is far more important than an offense that just keeps people happy. That 2019 team has Najee, they fed him the ball more and developed that running game like they did the following year, that season almost certainly goes better. Does that mean less passing yards? It does, but a healthy Tua and a championship seem like a good trade. I would also add it should have some value to keep running backs happy as well.
Other than that we can go back and forth but this QB hero stuff is not championship football. It risks the quarterbacks health, it doesn't protect the football, and it abandons the run. If I look at 2018-2022 I see fantastic QB play every single year but I only see championship football one year, that was the year I also saw fantastic running back play.
Having said that, this is probably Alabama football for the foreseeable future, and we'll always get mad when the QB has a bad game because it means Alabama lost the game.
Edit: I think you and I can disagree on a lot of stuff but I'd bet we'd both love to see another RB at Alabama with 1,500 yards and 20 TDs.
