Everything hinges on this.
If Purdy is above average (not great) and takes care of the ball, this window is very open. If he regresses and the Niners are forced to soon face paying another QB real money to take advantage of this D, they are in big trouble.
Sounds counterintuitive, but if I'm a Niner fan playing the long game, I don't want Purdy to be great, I want him good enough to win, but not good enough to be overly desirable during a contract year.
Fair.
I have no idea how this will turn out so won't pretend that I do. Maybe he's second coming of Brady. Maybe he's a flash in the pan and 4 games in they are turning to Darnold. I really have no idea.
If I'm betting tho? I think he'll be Kirk Cousins-ish. He'll play point guard and distribute in Shanahans offense...but when things go south and you need a special QB to will you to a win...I just dunno.
Kyle made the move up for Trey thinking he could be one of those special guys. He saw Allen at Levis just do near impossible stuff to win that game and decided he needed to get one of those guys. Honestly if not for what happened off the field I think Deshaun Watson would be a 49er right now. The 49ers would have made that trade instead of moving up for Lance.
I really like Brock, but he's never gonna be THAT guy...the rocket armed mutant playing QB. Maybe he won't need to be.
If Brock is special it'll be because of what's between his ears, what's in his veins, and just enough athleticism to keep him alive.
It'll be fun to find out.
