You've got double coverage, and it's on the OC for his QB throwing into that?
How many times has Tommy done the same silly mistake all year long trying to hit a HR ball?
As a veteran QB, if the play isn't there, you gotta know to eat it and get what you can or throw it away. If you have a QB who isn't willing to do that, no matter how many times he has been coached to do so, that's simply on the QB.
But it is on the OC to bench the QB that consistently makes bad decisions.
So we can put in Ryker Fyfe? See: Purdue
Armstrong is the less of all evils, sadly. That's the state of our QB position.
And as far as your post that the coaches do not coach him better - CTFO. That's just an absurd statement to think that Langsdorf just watches Tommy make this mistakes and doesn't preach to him week after week about the same thing.
