Manti, claims they met in 2009-10, so this is just another part of the ruse.
He claims to have met her several times, so things aren't adding up.
Either he was in on it, or he is the worst boyfriend in recorded history.
Your girlfriend of 4 years, supposedly, gets in a horrific car crash. She is diagnosed with leukemia, goes through treatments, is getting worse, finally passes away, has a funeral, a burial....and you never ONCE go visit her, if you had supposedly met her several times?
No way in hell he wasn't in on it.
When a guy is a high-profile football player with very little free time who lives thousands of miles away from home and surrounding by little to no Samoans, it is not crazy for him to turn online and try and find someone. If a 21 or 22 year old guy goes home for the holidays and tells his parents "hey, I've been talking to this online girl for a while" they would laugh at him. So telling white lies such as where he met the girl and how they talk face-to-face can keep him from getting any type of ridicule from family and jocks around him.
Hearing a voice, seeing multiple pictures, including one in which she holds up a specific name, makes things more legitimate. He has stated they became serious this year, so they made no trip to Stanford. Last year it has been confirmed he asked many of the Stanford players if they knew her but no one did.
The hoax probably got to the point where he was going to actually go and see her for the first time, and then the whole thing had to be blown up. It makes sense, since he probably had some off time for the holidays prior to the National Championship. With him about to make a lot of money, it was only a matter of time before he could personally schedule visits to see this girl.
However, I guess it is much easier to just automatically label him as definitely in on the whole thing.
