That's certainly a more generous way of expressing it, and here is what I found:
WGAM The Game » Matt Light
"In 2010, Houston alumni Sebastian Vollmer threatened Light’s rein as the starting LT and seemed to be great position to do so. After the 2010 season was complete the Patriots, not surprisingly, released RT Nick Kazcur and meaning now Sebastian Vollmer will have to be the starting right tackle for the foreseeable future with the stubborn attitude of Matt Light refusing to be switched over. The Patriots seemed to be in a bind with their offensive line situation until the 2011 Draft came around where Colorado star Lineman Nate Solder was picked in the first round by New England. Now Light must face the reality that he may no longer be in a Patriots uniform, unless he goes by the teams’ terms and not his own."
It seems like its an accepted opinion here in this piece. I remember first reading/hearing it about 3 years ago, and it was repeated several times. Not sure where it originated, but I made up nothing.
