Well he did miss 4 games in the middle of the season when he was coming off two monster games. I know, I know the “disastrous” 6 for 10 HALF against Minnesota was a sure sign he’s a lost cause.
Coming into the Washington game, he had a passer rating in the mid-80s. That includes by far his best passing game ever the week before.
Since the Washington game, he has a passer rating in the mid-80s.
For a turnaround, that's a mighty small sample size of actually good play.
And yes, he was bad in that first half against Minnesota. And also the entire second game against Minnesota. Those performances are not nearly good enough to keep him.
