I will never understand how teams are forced to play one set of rules for 16 games and then the playoffs start and the entire way the game is officiated changes, mainly the total disregard of the rules when it comes to defensive backs.
All of a sudden they can grab, hold, hang over them like a cheap suit, hit them all the way down the field and get there early on passes, but it's called letting them play.
Fine, if that's the way they are going to play it should be that way from week 1.
