This argument has gotten nowhere in months.
Jaylon sucked early after filling in for Hitchens early in the year. He was juked in the hole, made slow reads, plodded more than a little.
Everyone agrees on this part. I also think that for the most part people accept that he improved as the season went on. By the Atlanta game he was playing noticeably better.
The contention is in how much he improved. Personally, I saw him moving sideline to sideline much better, anticipating runs and routes based on formation, taking on blocks. Many think that position too generous.
Even more contentious is why he improved. There is a crew that insists that his play only improved from reduced snaps.
