The Pittsburgh Steelers, even on a flat cap, would be over the cap if the new league year began today. They have among the most difficult cap situations of any team in the league. Given that they seem in most eyes to be a team on a downward trend, that would seem to pose a bit of a problem—especially in an offseason with a number of key players heading into free agency.
The Cleveland Browns appear to be heading in the opposite direction, and have quite a bit of cap room. In fact, they have the most carryover cap space from the 2020 season of any team, of more than $30 million, since that was how below the cap they were a year ago.
