SEC Tweaks Rulebook - Effects Coaches and Kickers

Leaping and hurdling on extra  points and field goal tries is no longer on the up and up. No longer can you run forward and jump over  the offensive line to block a kick. You can, if possible, explode from  within one yard of the line of scrimmage, but no more running starts. 

Steve Shaw, the SEC's coordinator of officials, took the podium on Tuesday at SEC Media Days and said the following:  

"Now, the exception to that is if you're in a stationary position within  one yard of the line of scrimmage, then it's legal," Shaw said. "Then  you can jump. Now, it doesn't mean you can't run forward. You can go  through a gap. You can do whatever, but you just can't leap or hurdle."
