Our losses to Oklahoma, Tennessee, Michigan, and Texas had all one thing in common and that was all of them dared Milroe to pass and totally shut down our quarterback running game. They basically gambled that Milroe couldn’t read a defense and would be willing to live with the occasional big play when and if it happened as long as he wasn’t doing it all night.
This gets back to the root of the point I was trying to make. It wasn't a defense of Milroe, nor was it necessarily a condemnation of the OC, it was just that I feel over-reliance on the quarterback is a huge gamble that doesn't pay off consistently enough to win championships at the level Alabama expects to. For a normal team it's fine, but if you want to be in contention year in and year out it's not the way to go.
This doesn't mean you shouldn't have, or don't need good QB play though. That's not it at all, it's just that the unfortunate side effect of great QB play tends to be over-reliance as well. When I started researching this during Hurts time at Alabama, I immediately noticed that the indicator of success under Sagan was not elite QB play (it actually presented as a negative factor) but rather elite RB play. This was not that good QBs were bad in my opinion the result of two things.
A: When a team has a really productive QB the tendency is to just let them keep doing too much. This is an issue because it's gambling the team's success on the play of one individual at a position where a lot of things can go wrong.
B: This also doesn't necessarily mean that the running backs in those championship seasons were the best running backs Alabama has or what have you. It was just that if you did develop a strong running game and you stuck with it, Alabama's chances of a championship were really, really good.
A good example of this playing out was the year Mac threw two pick sixes against Auburn. Specifically, one thrown from the three yard line when the team has Najee Harris who would become a touchdown machine the following year. Mac wasn't the problem, the problem was not developing that smash mouth running game that would help the 2020 offense become one of the best we've ever seen.
The difference by the way was that in 2019 the Alabama team averaged 3.8 passing TDs per game to only 2.1 rushing. The following year that was 3.2 to 2.8. The quality of the passing game didn't go down, the quality of the running backs didn't improve. It was just about how they were used.
To give another example, I'll revisit Washington's 2022 loss to a team that finished the season at 3-9. This was a very good Washington team and a very bad Arizona State team. They'd lost four games in a row up until that point by double digits. Washington should have been able to club them like a baby seal. Instead Washington lost the game.
What happened? Penix threw the ball 53 times and then rushed an additional 6 times (well mostly sacks I guess but that's 59 plays he kept the ball on). This against a team that hadn't scored more than 25 points against an FBS team all year! He threw one interception, 0 TDs, and they lost by a TD.
Why on earth is he keeping the ball 59 times against a team that over-matched? They weren't down big, it was a one TD game almost the whole way, yet he's holding onto the ball 59 times. May be the running backs were ineffective that game? Not at all, the running backs averaged 6.8 yards on only 25 carries (170 yards) and 4 TDs! That's how you lose to a team that you're way better than, you play QB hero ball when you don't even have to.
So... a very long story short, I think the key to success is to make sure you develop and utilize a strong running game and then intentionally try to limit over-reliance on what is hopefully a very good quarterback. You unleash him when you absolutely have to, but otherwise the goal should be to balance his utilization with maintain a strong running (back) game. You can't afford to let them team overly rely on the quarterback to win games and you can't afford the quarterback getting into the habit of trying to win the game single-handedly. That's how you lose games like Arizona State, Oklahoma and an Auburn team you really had beat.
