The Panthers received a league-high 112 kickoffs last season, which was the most in the league by a wide margin. (Setting an all-time record for points allowed in a season means the other guys kick off a lot).
Of that total, 66 were touchbacks taken at the 30, which was tied for fourth-most in the league. Under the proposed rules (which will have to be approved at next week's owners meeting), that could have been another 330 hypothetical yards for the Panthers last season.
But the math isn't that simple since the new rules would change the incentive structure for teams (teams were causal about giving up the 30, but won't be about the 35). Competition committee chair Rich McKay told reporters that [the league anticipates the rate of returns to go up to between 60 percent and 70 percent if the recommendation passes](https://www.espn.com/nfl/story/_/id/44417228/nfl-competition-committee-pitches-making-dynamic-kickoff-permanent).
Last year, only 32.8 percent of kickoffs were returned in the new "dynamic kickoff" setup, up from 21.8 percent the year before when a touchback placed the ball at the 20.
