I've been thinking this since this issue even surfaced. A QB should be able to prep a football pretty much however they want, short of shredding it I suppose. If they start with the same football, then whatever. If the goal of the league is to have good offense, which it is, then minute rules about ball pressure don't make any sense. I'm not claiming that the Pats don't seem to have violated a rule, because it does appear that way and they will get a punishment, but why even the rule?
No QB will throw a 1 psi ball, because you can't throw and catch a flat leathery blob, so every QB will naturally be within some sort of range that works for them (9 psi to 14 psi maybe? Maybe they change it a little with temp and the conditions? Does it matter?). Why should anyone care?
I care most about CONSISTENCY OF THOUGHT, and this often comes up in political arenas as well - I have no trouble with democrats, republicans, libertarians, socialists, etc, as long as their thinking is internally consistent - if they have a logical view of the world that all works together for them. You just can't have incredibly low taxes and generous public programs - those two aren't internally consistent.
Having a minute rule about ball PSI, though, isn't consistent with wanting offenses to rule the day. If this rule had been changed in the offseason to allow whatever psi anyone wanted, NO ONE would have cared, but instead the NFL messed around with defensive pass interference emphasis, and it's been a HUGE point of aggravation for players and fans this season.
I just hate the inconsistency, because it's pointless.
