The only thing is ... you can't legislate effort.The precedent having already been set the other way, legislation will be required.
Most of the Hot Dawgs (on both teams) never put their shoulder down, attempting to gain another 2 to 5 yards anymore but, rather run out-of-bounds. Hell, that Mizzou DB went into his slide, in the middle of the field, before any Carolina players were within 5 yards of him.
But, I will tell you what, watch the game replay and notice that on virtually every single play, some Hot Dawg is either fist pumping or running down field 40 yards while self-praising themselves for being involved (didn't necessarily MAKE-the-Play, just needed to be somewhere close by) so they can pull out their 'Little Boy Pretend Guns". It has gotten ridiculous!
