At the 1/2-way point, you look at the AFC and this was supposed to be a slug fest with all these teams, and it still is to some degree.
Mahomes - Is still Jordan.
Herbert - Lost his #1 WR for 90% of the year, and that team is struggling to score more than 22 ppg.
Burrow - Offensive Line has plagued them, but he is still capable of huge days.
Wilson - Regressed
Lawrence - Better, but has not taken the leap.
Jackson - Playing good, not better than ever though
Tua - Has impressed. As Nate Z said on WGR, the football doesn't look pretty, but it gets where it has to be.
Tannehill - The Titans offensive personnel peaked a few years ago and hasn't been the same since
