If you want to give people shit about their positions but don't have the time in your busy schedule to try and understand their positions...then's there's not much point in having a conversation.
I will make it short:
Steelers hired the wrong coordinator, signed the wrong vet bridge QB, and may as well take it on the chin and see if they drafted the wrong QB. The cherry on top is that the BIGGEST competitive advantage currently afforded NFL teams is having a rookie deal QB that can play decentish. May as well see if your franchise can access that cheat code.
