They judged from training camp throughout preseason. I don't think it was a mistake because clearly he was making plays. I'm not sure how much room they had to anticipate he wouldn't be ready during the live games. His case happened a bit different from Fountain, but they both when all the smoke cleared needed to sit and learn on the PS a little bit.
Fromm is basically an upgraded Jacoby Brissett, a high-end game manager that won't turn the ball over and makes enough plays to win you some games. I'd take Fromm over JB.
I'd say take a guy like Jordan Love or Jacob Eason with the Redskins pick and develop them for a year under JB. End of next year, stick with whichever guy you're more confident will take you where you wanna go.
Once Funchess hits the field either this week or next and assuming he gives us solid production throughout could we not just rework the contract if we want to bring him back? I don't see this as a total waste with the 1 year contract he received.
