I started watching Alabama football around 1996 and for the longest time, we didn't have a NFL caliber QB. Then, we have a stretch of QBs: Jalen, Tua, Mac, and Bryce. These are all QBs that are starting for NFL teams. Now, we had a couple of QBs that had very brief stints in the NFL like Brodie Croyle and AJ McCarron, but no true NFL caliber QBs until those four names mentioned above. The early championship years of Saban's tenure, we relied on great RBs, great defense, and a game manager QB that could make a couple of big passes a game. That was the formula for those early championships. The formula for the recent championships has been high powered offense, great receivers, good running backs, and NFL caliber QBs. The defense in recent years has not been suffocating and is more akin to "we'll stop you a few critical drives a game because our offense will score so many points to cover our weaknesses".
This year, our QBs are our weak point. Other college football teams face this reality from time to time and this year it's our turn even though we supposedly recruited well getting Ty Simpson. But, Ty is not there yet. Jalen honestly isn't there yet either, but he's the lesser of the other two evils and give us the best option with his ability to run from pressure.
