Wow. I haven't been keeping up with this at all, but it's crazy. Either he's an (1) unintelligent sociopath or (2) really gullible. Honestly, he's Manti Te'o - he could probably get a lot of girls...even a lot of dying ones, if he actually was a sociopath looking to make a good story.
I choose #2 - I'm thinking that he's just extremely gullible and too afraid (stupid) to admit it, so he doubled down on the stupidity to try to cover it up and make it sound real. If other people around this situation that care about him (his parents) have lied as well, I'm guessing they did it as a favor or to try to protect him somehow. They ended up just adding to the mess though. What a mess it is.
As most people know, you don't have to be brilliant to play football decently and get drafted. It would have been okay to just tell the truth (or just not tell more lies). Now he has to deal with being called a sociopath instead of just an idiot...Maybe he prefers it that way, I dunno.
Oh well, I'm sure some team will draft him anyway since his character issues aren't criminal, as far as I know.
