Damn, it I typed up a long response, and then it didn't post. Short answer, I agree with Sam. These are probably the two rule changes that most aided opening up offenses, but the hashmarks at least also helps the running game, particularly the jet sweeps that MSU adopted very effectively last year. I do miss the WLB/SLB distinctions mattering so much. I did enjoy the strategy in the more traditional or wishbone options of running it behind your better blockers towards the shortside of the field, or going wideside but behind your worse blockers. So, I'd prefer eliminating both rule changes, but of the two, I'd rather go back to actually calling holding on pass plays. At least they started calling ineligible man downfield on RPOs last year.
