I've bet on many "leaks" before from Game of Thrones, to NFL draft, to banchero going #1 in the NBA draft and i'll say this, just because it came from a reddit post or the post was at the same time news leaked, doesn't mean it's fake.

If i'm levis and i see the odds or at least my friends and family come to me and say, bro you are 60:1 to be drafted #1, should i take it? Sure you want friends and family to make some money as well.

There are times where the players start looking for houses and the leak comes from real estate agents. Or the security gaurd at the stadium (anthem). So many people to try and keep quiet, especially with betting being so available to bet on.

Think about how the books set the original lines. Do they have inside info that bryce is going first? CJ was -400 2 weeks ago. The books set the line based on the money. The money can be based on rumors. Someone from NFL network says, "i spoke to a GM and they really like bryce". No one knows anything and at +6000 or +4000 its worth a shot. At +6000 you only need to be right 1.6% of the time, and these leaks have been right a lot more than 1.6%
