Sadly my thought is if the Browns don't get over this kicker obstinacy soon it's really going to hurt them. I'd hate to see the Browns fire everybody because they can't make a FG. Cade York is the Nuke Laloosh of football. ( the pitcher that dropped the mascot in Bull Durham) They like him because he has great stuff but he has no clue where it's going. Why is he kicking curve balls? Hey Meat hit them straight! Should somebody tell him to aim toward the Elf? Do the Browns have the time to wait for this kid? Idk I'd like to see them with a plan B.
If it really came down to that, I doubt we would fire everyone.
As for a plan "B", you can execute that in a day. You could do it as early as the Friday, even Saturday before the game. No doubt that earlier would be better...so sign the guy on Monday after the game and have him in camp by Wednesday.
Kickers don't have playbooks to memorize or anything like that. He and the holder only need to work together for a few hours tops before the holder gets down the placements the way the kicker likes and the kicker becomes comfortable the holder is going to get it down to his liking.
Send the snapper, holder, kicker, a few ball boys with a sack of footballs down to the stadium for a few hours and you are good to go.
