On the other side of that coin: does Ty Simpson run for 155 yards and 4 TDs against LSU? Does he kill Ole Miss, Texas A&M, and Tennessee over the top with multiple precise deep throws to Bond and Burton? If our defense lays a bit of an egg against Auburn like they did, does Ty make that read and that throw to the corner of the end zone to Bond? Does he play with incredible poise against UGA and help us generate an unlikely win throwing and running? He might, we don't know for sure but Jalen won the job for a reason.
I see the point you are making, we went with a guy who was more limited in terms of being able to run the entire playbook and make reads, changes at the LOS, etc.. That said, Milroe accounted for 3,365 yards and 36 touchdowns this season (and that includes missing an entire game). A number of folks will have him near the top of the Heisman list next season (he barely missed getting an invite to NYC this year).
I can't get behind the notion that the staff made the wrong call. He might not be able to audible at the LOS, and he might have to look to the sideline, etc.. but that doesn't necessarily make him any less effective. It might mean that he won't be a great NFL QB, but there are literally tons of guys who were super effective in college and weren't great pro QBs. Our objective is for him to be an elite college QB. Not sure if the guy has the skill set to be effective in the NFL but honestly that doesn't matter for our purposes - and I know the next question some may have have is "doesn't that hinder recruiting?" As in, you aren't developing NFL caliber QBs. I would usually say the answer to that is "yes" but the caveat for us is that Milroe is an outlier - it's not like we run Malzahn's offense and we can point to Bryce, Tua, Mac, etc. who all ran variants of the same offense and have been NFL starters. I think we ride Milroe as long as he's our best chance to win and be very productive on offense - and heck, if he improves as much next year as he did over the course of 2023 he may very well end up in the thick of the Heisman race.
