If this proves to be true there should be no further mention of extortion:
"According to Murtha, that report is accurate but incomplete. Martin had promised he would attend the trip, which was paid in advance. Martin then backed out at the last minute, not due to illness or family emergency, but because he no longer felt like going. The players who helped organize the trip, including Incognito, demanded Martin still pay his share because everything was pre-paid, and there were no refunds available."
"Obviously, IF this version of the story is true, the Vegas trip being partially paid for by Martin no longer qualifies as an example of bullying - I've done the exact same thing to a very good friend of mine in a similar situation.
It's not bullying to expect friends to keep their word. This could be an example of a story sounding much worse than it is in reality because of a key detail missing - in this case, Martin allegedly promising to go on the trip, which was pre-paid."
