It doesn't matter who is QB, we will have no passing game. What does it matter if it is 150 yards or 50 yards?
If Morgan is in the D can key on Tucker as there is zero threat of a QB run. Additionally Morgan will not avoid the sacks that Shrader does. So you really want to trade more sacks, a less effective Tucker, and no QB runs all for 100 more yards passing? And that is assuming Morgan doesn't have a Louisville like performance and that our WRs actually catch the ball.
Our best chance at scoring is breaking long runs. Our best chance of winning is a low scoring game which can't happen when the D can't make a stop and STs suck.
This team is complexity broken, way more than just the QB. I don't doubt Dino starts the year as HC next season but hopefully the new AD picks a good replacement next December.
