So you start Peterman, crush his confidence, cocuss him repeatedly, or he just sucks against live bullets. Very low chance he succeeds and gets what most want, which is the playoffs. So then fast forward to next year. Draft a QB right out the gate, then are forced to start him because you let Tyrod walk and the bridge you had lost his confidence is a concuss-a-matic or just plain sucks.
Then rinse repeat with the high draft choice.
I would stay the course, develop the new line pieces. You could put anyone behind this line and it is going to be tough sledding. Tyrod is fine for this season.
