How exactly do you know all this about Manti Te'o? I'm not saying he isn't all these things you're insinuating but all you or I know about Manti has been defined by the media and PR flacks. This same media who did ZERO fact-checking on a dead girlfriend.
Unless you're a close personal friend of Manti or a person who raised him, we have no idea who the real Manti is. 2 years ago, Lance Armstrong was an American hero that fought tirelessly for cancer research and redefined the sport of cycling. Because that's what the media and his PR team wanted you to know about him. Fast forward, and he's a doping, paranoid freak that duped a nation.
We know NOTHING about Manti T'eo other than what's been carefully presented of him.
