By Bill Bradley, contributing editorPenalties for hits on defensele s players have been cut almost in half this season, falling from 35 fouls through 10 weeks of the 2013 season to 16 so far this season, according to NFL vice president of officiating Dean Blandino."They're substantially down," Blandino said during his weekly "Officiating Review" video distributed to the media Friday. Phil Esposito Jersey "Players are adjusting. The coaches are adjusting. That's a positive thing."However, Blandino said there has been a slight increase in illegal blindside blocks."The blindside block is when you approach your opponent from behind or on the side; you're blocking back toward or parallel to your end line and you make contact with his head or neck area," said Blandino, who showed an example during last Sunday's - game. "That defender gets defensele s player protection. You can't hit him forcibly in the head or neck area and you can't hit him with the crown or the forehead parts of the helmet to any part of his body."...

And when we talk about the umpire and referee, they have got to be deeper than the deepest back so they can effectively officiate what they need to look at."Blandino said he thinks officials have been very efficient when working with hurry-up offenses Clark Griswold Jersey . However, the crews will continue to work on this portion of their game."We don't want to prevent the offense when they don't substitute from being able to get up and efficiently snap the football," he said.
