What they are going to do is obvious and shouldn't/won't be controversial at all.
You ride it out with Darnold as long as you can even if it means McCarthy remaining on the bench for longer. Give him a Geno/Baker type deal that they can move on from a couple of years down the line if he regresses considerably.
No need to rush to trot McCarthy out there. No way in hell should they let Darnold leave the building.
You say it like it's obvious, but the Falcons got roasted for trying to have a 2nd QB in the wings and the Packers catch hell from their older QB every time they do it.
Not a lot of team would do what you're saying. I'm not even saying you're wrong. I just think it'll be entertaining to watch them hem and haw about it. Kirk Cousins is the most passive person of all time and he was salty watching them draft Penix.......plus the extra bonus is I'm not sure Darnold doesn't come crashing back down to Earth. We saw it happen to Nick Foles before.
