Actually, that's not the case.
The distance the kicker has to kick the ball hasn't changed since they moved it to the 35, and neither has the desire to do so. It wouldn't make sense to purposely try to kick it shorter, because you still would only need a 20-25 yard return to cover that, which is pretty common.
What this rule does is give returners less motivation to bring the ball out of the endzone on a return, because they now have to go 5 yards further to get back that yardage.
So the first rule, kicks from the 35, makes it easier for kickers to kick touchbacks, thus reducing returns and reducing collisions from returns.
The second rule, TB at the 25, makes it harder for players to gain back the return yardage when they do return it, and makes it riskier to bring it out of the endzone, thus reducing returns and reducing collisions from returns.
I will 100% guarantee that touchbacks will increase in 2016, and kickoff return attempts will decrease in 2016. Precisely what they want.
I dont think so. yeah teams will be less likely to bring it out of the endzone...but because of the extra 5 yards they'd be giving away, balls probably wont be making it to the endzone anymore anyway, so its a moot point. Only half the league averaged 24+ yards on returns last season. Only 9, got 25+. http://espn.go.com/nfl/statistics/team/_/stat/returning/sort/yardsPerKickReturn Half the league will still likely lose at least 2 yards if forced to return it. Its a game of inches, so many will find it worth it. Aside from that: it will always make more strategic sense to give your coverage unit a chance to stop a returner than to guarantee them 25 yards. Kick it high and short and run him down. If he makes it back to the 25 anyway, so be it,but nobody's just gonna gift drop it for them though. Harbaugh has the right idea, and thats probably how this is going to go with most teams.
