My point all along has been "it ain't over until Saban says it's over".
There's not one person who has posted in this thread who believes without a shadow of doubt that Tua is better/will play more than Jalen/eventually takes over the position who doesn't agree that CNS has the final say.
Your comment seems to suggests there's some unseen or unheard knowledge about Jalen that we aren't considering that CNS has knowledge of that will suddenly make Jalen more desirable and a better fit for the position.
Of course, I'm not saying we know more than CNS, but unless Tua has an attitude problem or something real negative that only CNS knows, it's pretty much an open book on the two as quarterback prospects. Shoot, I'm even of the persuasion that we've only seen the tip of the iceberg with Tua's talent and even at that it doesn't seem like there's much hope for Jalen to be the #1 QB. Based on the A-Day game and CNS's comments on the hot mic, he might even be looking up at Jones ahead of him.
So yes, CNS has the final say, and I don't think it would surprise anybody if he ran Jalen out as "the starter" against Louisville, but I don't think even the strongest advocate of Jalen on this board believes he's "the starter" for more than the first game.
At some point football 101 must rule the day. That's how simple I think this is. If it doesn't work out this way, I'll admit I was wrong. But what would it take at this point for Jalen to actually beat Tua out and lead this team that has not been previously on display?
