The point is that this rule makes no sense in 2015. The NCAA and the ASA should scrap it.
If enough can't slap while keeping both feet in the box then allow one foot out for 2017 even though it made sense when they established it in yr ????. I don't mean it smart*** as that sounds I'm just not a fan of rule changes to accommodate some that can't play / learn / dislike a rule(s) that so many before them played by with great success.
I'm thinking obstruction and interference are outdated, at least for my team, y'all leapers should still follow it.
