Don't make uninformed assumptions that cast aspersions on the reputations of these people!
First of all, that quote should not be attributed to SkinsFan09. It was either Mr. Yeti, who runs the very informative "Black and Blue" blog that covers the Lincoln Stars and was possibly repeated by Mr. McMahon who blogs about the Merrimack team.
Mr. Yeti is personally acquainted the players in Lincoln. By May 2012, there were three Lincoln players who were committed to NU for this season and one for next season.. For all you or I know, there might have been a comment made over beers that that led him to suspect that Roy might reconsider his plans.
Despite your anger and disappointment, is it conceivable to you that Roy, and the three recruit pals, might have heard that NU had two scholarship players turn pro in late spring? Perhaps, at the urging of his friends, Roy may have made a call to the coach who recruited him two years earlier, at which time he inquired about NU situation and their possible interest in him. That is the proper "etiquette" when someone wants to decommit and go elsewhere.
I don't know how this all came about, but I do know that it's foolish to jump to conclusions without knowing the facts. It's even more foolish to share such conclusions.
