he had a total collapse of any player I have seen in a very long time. he was on fire early in the year. he was good last year. he was improving. and then since the denver game, it was a comedy show. his foot work, the most basic fundamental for a QB became worse than I have seen in high school kids. I pointed to that multiple times, on how bad his foot work was. and it didn't just become bad, it became worse progressively. you do that as a QB, you are inaccurate. then that reverted him back to 2018 when he was holding on to the ball too much, because he didn't trust himself to make the throws and had to see player wide open to throw it and even then he missed often. he used to be good throwing on the run, but he became bad and was better from the pocket (when he was forced to kind of set his feet before throwing). moving to the right was a wild ride, high throws, too far throws. throws to the ground. he was plain bad running to his right and throwing. all of that led to him playing without confidence, lack accuracy, hurry his throws or hold too long, not trust himself and plain sucking.
I maybe over simplifying, but he has to go back and clean up his foot work, else he will sink further. play more desparate and collapse even further than he already has. yes. its that simple.
