This is where his dad always being his HC hurts his development. As a NFL QB, you have to be able to take the quick and short yards when it's there. The big play is not always there. You don't always have a Heisman WR making big plays for you. Even if you play with the 1s, you will still have a lot of games that 3 seconds throwing window is all you can have in a lot of snaps.
Most QBs had to learn this in college. For SS, even with TB12, a master of doing this, as his mentor for a long time, he still hasn't learned this. Because he doesn't have to, no one is able to hold him accountable because of his dad.
SS doesn't like option route? Sure, fire the OC. SS doesn't like run play? Sure, audible to whatever you want.
We have had many arguments about this last season, to me, the OC of Colorado is always SS. Everything we complained in the last two years, super bad OL, zero running game, zero presnap motion, is because of SS as the OC. I think it will become very clear once you see the Colorado offense this year.
I truly believe the best development path for him is to sit behind an established QB1 for 1-2 years to really learn how to operate a NFL offense. It sucks that he is in the worst organization that has no stability in QB position and has a another long term backup QB drafted before him.
The best situation IMO is that Brown draft a new QB next year, keep DG as the backup QB, and trade SS to another team.
