There are smurfs in the NFL getting it done. Not saying he's anywhere near the level of a Drew Brees or Russell Wilson... or even Baker Mayfield. But he's serviceable. He's smart, tough and can manage a game. He's a shorter version of Alex Smith, basically. Team can build around that and honestly... if a Brad Johnson and Trent Dilfer can ride the coattails of a great defense to a Superbowl win then so can he.
I say... stick to what's working. Keep building the trenches. You can never invest too much in a good O-line or D-line. We need better cornerbacks. If a great QB prospect lands in our lap, sure take him. But I'm comfortable running with Taylor Heinicke as far as he can take us.
