I generally appreciate and agree with your observations but IMO, Jalen has made definite progress this year, even from the poor performance vs Louisville to the last 2 games. Both TDs vs AS were throws he might not have even attempted last year, including one where he was drilled by a rusher. He also tossed the ball out of bounds on one of his patented "drift to the right and run OOBs" plays. Yes, there are open receivers he has not seen or didn't pull the trigger on, so it's been mixed. OTOH, he has made observable improvement including reading the field and pulling the trigger on throws he would not have made last year. I think Enos and Tua are helping him and rather than pouting, he is a willing learner. CNS understands the vast difference between the abilities of the two and IMO, appears to be handling the situation in a remarkable way.
As an aside and on a related note: if things transpire as it seems - that Jalen is going to play the year as the willing backup - it is a great testament to the environment and atmosphere that Coach Saban has created and even more to the character and personalities of Jalen and Tua.
