I thought he was just coming by for a seminar?
Also,he should just take a trip up to NYC with him so they get the footage up on Mginaction.
That said, Ryan is a much more elite no-gi grappler than Reilly (And i am a HUGE Reilly fan), but realistically in a highly competitive roll I would expect it to be less exciting than them flowing, because there would be a lot of time spent just smashing from half guard.
I'd be much more interested in video of them both discussing a technique or teaching together, because they both have a similar teaching approach.
