Even though I am not a Broncos fan anymore, their defense does deserve a little blame for their record. In three games now this season, the other team had the ball in the last two minutes and trailing, and the Denver defense let them come down to score to either win it or tie it. Gotta get those stops.
As for Wilson, yes, he has been terrible this year, but keep in mind he has a terrible coach, a horrific o-line, little to no running game and no WRs (Sutton hasn't been good since 2019 and Jeudy is unproven as a pro). I think he could turn it around next year if all or most of those issues get resolved.
