Teams should no longer possess footballs on the sidelines. The NFL should be solely in charge of football maintenance.
I think the league realized at some point that their rule is kind of silly (really why 12.5 to 13.5 PSI, what the great tragedy of 12 or 14 or even 10.5) so they’ve kind of taken to ignoring it. The league used to be solely in charge of that, but nobody liked it, and it didn’t work either:

As the MLB has learned repeatedly over the years, the players have a way they like the football and they’ll do what it takes to make it the way they like. The more this thing has banged around the more I’m with Aaron Rodgers (from before this whole “controversy”), it shouldn’t even be a rule, let the QB setup the balls how he likes, as long as it’s not completely retarded (like stickum) who cares.
