all year sea cluks allowed to cheat by mugging all the teams they played wrs. tes .etc.everyone knows sea punks old rogers prefer team in superbowl.the one play lance did very minor push off to catch pass it looked like the refs almost broke arms to throw flags what a joke.Fair refs saints easy win.same for pattsys game you could show tackle holding junior kneck in choke hold an also by waist band of junior on brady last sec td pass,as a training film for refs when to throw flag.if flag thrown as should have been plus several other strange calls game over saints win an at home for playoffs nope old roger shafted the team all year long.

I hate to say this but the head of officiating tweeted that the Hawks aren't even being looked at by the league for holding or grabbing, basically implying the Hawks are clean and other teams are the repeat offenders. Those waiting for a flag are going to be waiting a looooooong time. Not sur why people perpetuate this rumor but carry on.

It's not going to be a long time. The NFL rules committee announced they were going to crack down on defensive holding, illegal contact and pass interference this season.

Mike Pereira made that tweet about the hawks not being looked at, when he was reporting on the rules committee meetings. There was no implication that the Seahawks were clean only that none of he examples given during the meeting were of the Seahawks.

In fact Mike Pereira agrees the Seahawks do hold and get away with it.

The Seattle Seahawks—the favorites to make the Super Bowl out of the NFC—employ an exasperating defensive game plan: They blitz rarely and drop an army of defenders into pass coverage. And those defenders mug, obstruct and foul opposing receivers on practically every play.

Quietly, the Seahawks have achieved a 13-3 record and home-field advantage throughout the NFC playoffs by exploiting a loophole: NFL referees are reluctant to throw endless flags for pass interference and defensive holding, even if defenses deserve them.

"They look at it and say, 'We may get called for one but not 10,'" said Mike Pereira, a former NFL vice president of officiating who is now a Fox analyst.
