I don't know jack shit about anything, but if no one else is willing to step up to the plate, I'll certainly take a crack at winning some type of prize.
I'd suggest that no matter what sport you want to handicap, you familiarize yourself with the teams and players as much as possible. That means actually watching them with your own eyes on TV...if you're knowledgable on sports at all, you'll be able to formulate your own opinions on players and coaches, the team's style, etc. and then be able to implement that knowledge into your handicapping.
For instance, if you watch a basketball team on TV and, win or lose, they impress you with how they play, toughness, etc., you'll automatically make a mental note of it and apply it in the future, as opposed to just looking at records or stats and being like "oh, well team A averages more points than team B. They must be better." Sports are about a lot more than stats, IMO.
I have no idea really what I'm talking about, though. There are plenty of guys on here who have been doing this for years successfully who could help you out.
But if they're unwilling to post...I'll take a personalized video of you masturbating and bringing yourself to a bunch of ridiculous orgasms. Real of course, none of that fake shit. That will suffice as my prize. Make a note, GD.
