The NFL's vice president of officiating Mike Pereira said Sunday he's interested in a job "that would redefine what your idea of an assistant coach is.'' Pereira, who turns 60 in April, hopes to find a team interested in taking him on when he leaves office in May. He believes he could train the team year-round in penalty prevention, working with the coaching staff on what makes officials reach for the flag on touchy calls like pass-interference, and then be in the coaches booth on Sunday upstairs telling the head coach when to throw the challenge flag. "Say the average team gets 10 penalties for 75 yards,'' he said on a couch at the meetings here. "That doesn't count the calls that weren't accepted. I believe penalties have a bigger impact on the game than anyone realizes. I'm fascinated by the coaching aspect of it, of trying to cut down the penalties. Obviously it's never been done before, and I realize not every team would be interested in something like this. I think it's a matter of who's progressive enough to think about it. Who would take the chance?'' Source: Peter King, SI.com
