As I posted in the other thread, if you want to play with a 10.5PSI ball on a cold day and also follow the rules, simply inflate the balls to 12.5PSI in a very warm room, have the refs inspect the balls and when the balls go outside in 30 degrees, you'll have yourself softer footballs after the air temp drop in the balls. That doesn't break any rule. Smart on their part if they did that and if that it what they wanted. I'll bet other teams do it too. A high school kid could figure this out. The NFL needs to change the rule or simply allow teams to uses balls inflated to whatever pressure they want outside of the kicking game.
