I looked up his name and it showed he signed up not even less than 10 minutes ago..
His gamertag is apparently his name.
Look up " Marcus Thornton"
Anybody verrifythis?
Sorry I don't no were to puT this...
It's probably not him, if you search for every NBA player on XBL, you'll probably find a gamertag for everyone of them. But, it won't actually be the real person.
