I'm on the MV point of view on Erik. Everything that I've heard about Erik's involvement with GW points to a multitute of factors that have led to his signing. In no particular order:
His uncle being here,
Hobbs - he has a LONG relationship with Hobbs - Many years
Really liking the other guys on the team,
Being closer to home (Philly) than a lot of other schools,
His mother being comfortable with, Hobbs, GW, and DC.
If any of those factors aren't working then it might not have worked.
Don't forget that Erik's mom almost certainly has a lot more influence over the situation than does his uncle. People talk like he is simply a commodity that Roland can just take with him wherever he wants and I think that is incorrect. Erik and his mom are first and foremost interested in what's best for ERIK - not uncle Roland. As it should be.
