Isn't it obvious? It's not that we're interpreting rules too loosely. Officials have just gotten THAT good over the last few decades.It's rugby now lol. Watching black and white FILM from old collegiate or HS games makes me laugh now: the rules are not in any way, shape or form even remotely related to those of yore. Reach in, over the back, traveling, carrying, push-off, moving screen. Antiquated ideas apparently.
