re: The slowdown rule does NOT affect only a couple of plays per game

Just some ideas ...They need to extend the players area on the sidelines to go from goal line to goal line. That way the d can sub in easier noatter where the ball is on the field. They could also change where the ball is spotted, adjust the hash marks closer to the middle ( I think this was done not long ago? ) and they could allow for the defense to sub on first downs without the on snapping the ball until subs are in and that would also give time for the chains to be moved and the refs are set.

FTR: I don't really care if the rule is passed or not and I see both sides of the agruemnts. Back in 08 when the rules changed, 25sec clock moved to the 40 sec clock, there were a lot of coaches talking about how it would be a huge benefit to the HUNH and it has which is why more teams are running the system nowadays.
