I believe we all need to sit back and slow down on the assumptions Tua will be the next Montana/Elway/Favre combination quarterback.
Teams have had 2 years to figure out Jalen Hurts, and they essentially did. Alabama is the one of the most watched, analyzed, scrutinized, and dissected teams in the country. Tua MAY be great coming out of the first game and never lose his composure or a game, or he may have had one of those other-worldly games some QBs have. We will have to see if he's durable, consistent, and teams can't figure out how to scheme against his (if any exist) weaknesses in our playbook.
I'm optimistic, but it seems people are losing their heads thinking he's going to score 7 touchdowns a game. Jalen scored many, many touchdowns with his feet, which made his overall effectiveness better than most quarterbacks in the country. Jalen's passing problems are overly well documented in these threads, but so many have forgotten how good at game management, composure, and staying healthy he is.
I wonder if Jalen had one of those typical "sophomore slumps" so, so many QBs have.
But, I sure hope what we saw from Tua is the norm, because he played the best I've ever seen an Alabama QB play off of the bench and maybe even ever against a very good defense.
