I love the new rule that moves the coaches back 2 yds during a live ball. I had a feeling that could be coming when they moved the chains back a couple years ago. Safety is a larger issue now with lawsuits being filed. A few years ago a chain guy in SD was killed on a sideline play.
Another side effect might be less hassle from coaches because they are farther from the play and can't see it as well. OOPS! Silly ME!
