I have seen a general thought, that qbs with coach fired after first year do not achieve success. New coach, new thought on what type of qb needed, less investment. Throw in front office here too like you mentioned. Also new scheme, terms, playbook. Tough to recover from.I am getting worried that Poles does not like Fields. This lack of focus on the offense is crazy.
I'm not worried that Poles doesn't think Fields can play, everyone knows he can, I'm more worried that acting like it wasn't his choice is a way to extend his lifespan in that job. Can always just say that wasn't my qb pick, gets to pick his next one, and that gives him 3 more years minimum.
