I won't say how I know, but I do know that every year, and after every game that Hawaii does NOT cover the spread, the HPD and FBI receives calls that their is point shaving.
From what I hear, this goes on for almost every football program. (a team doesn't cover, the police get calls)
I also knew of this investigation weeks ago, and I also know a lot of details that were getting preposterous. The rumors were just getting plain outlandish.
I know many players on a very close level, and in fact know exactly where they are on their days off.
Of the main players I know, I would say no way in the world this is true. I cannot vouch for fringe players.
Someone needs to say, "Ummmmm, Hawaii has the most injured starters on offense in the NATION. Of course they will fucking struggle!"
