That new rule is destroying the integrity of the game.
Your guy misses a contested catch at a crucial time? Challenge that there was PI on the play. Every time. I would. Even if there is only a 10% chance of it working.
The other reason why it's lame is that there are rarely missed calls as blatant as the one in the saints game. So because one time the refs blew it, they change the rules of the game. -absolute stupidity and as usual the NFL caves to any pressure disguised as "the right thing to do".
