The source, even with its 'Idiot's Guide to Rugby', fails to notice that there are 2 completely different codes of rugby - 2 sports called 'rugby', 'Rugby Union' and 'Rugby League'. League, which is what Crowe is into, is much closer to American Football, so while it might be easier for Americans to understand I can't see it catching on. What would be the point? I might be wrong, but to me it seems like it isn't different enough to seem like a worthwhile thing to get into. Union is a very different game, though, so might be of more interest as a separate sport.
I don't know about League, but union is already played in the US, of course. Whether it will ever catcvh on big-time I doubt, though.
Here's some union highlights from last year's Rugby (Union) World Cup, anyway:
