In the case of Petras he never actually made a decision he died on that hill... He's made some changes here and there but like you said it's NEVER immediate. Feels same with Hill this kid has struggled. I'd have liked to see Labas get some reps in 2nd half of that game. Or hell even Lainez too what would that hurt at this point?We have been through this type of thing before at various points:
Hey Kirk, you know running a base defense where your elderly DC never calls a blitz is not going to work in modern football.
Hey Kirk, your best friend OC is a terrible playcaller and is holding you back.
Hey Kirk, using your MLB to cover a WR on the boundaries is incredibly dumb.
Hey Kirk, um, kids gotta have access to social media. Its 2019 for pete's sake.
Hey Kirk, Christensen can't hit a 5 yard crossing route. Ever.
Change is never immediate with KF.
For a qb to have as poor of a game as Hill did with the weather not being a factor or anything else is pretty unreal. Then to not even entertain the thought of getting others reps is even more wild. Get the other guys reps and see what they have. They can't be worse can they?
