Wasn't this exactly how things went last year? Coaches insisted on a certain play style, and finally after about 6 or 7 games they allowed Fields to run more and he had decent success? Yeah I get it the team was still losing games, but they went from losing while scoring 10-12 points/game to losing while scoring 30-33 point/game and keeping it close instead of being curb stomped.
Well, they likely realize that Fields running like that is generally unsustainable and they'd like to protect their investment.
Fields doesn't have a huge contract and if wants one he'll need to earn it and playing the way he's playing is not going to get him there. He's not going to earn being a 5 step drop qb, that's not his skillset. I understand your point but you can't take the best skill a player has away from them and then say "go be great!". I get why they might want to move in that direction but the results speak for themselves.
He was awful year 1
he was awful year 2 through the first 5-6 weeks
he starting running like mad and became the #1 FF QB the rest of the year
Year 3, they give him weapons and have him stay in the pocket and he's been terrible.
I see a pattern....
