I have been on PreGame for a few years now and followed/bought different cappers with varying success levels (which is to be expected).
The best follow and best money I have spent is on Dave Essler. Yes he is hot right now...great streak, but that is not the only reason he is the best follow.
While winning money is important, Dave really lets you into his head about why he is on the side of a game. He approaches the game from a statistical and game strategy standpoint and really seems to be able to blend the two into a write up that makes sense. It isn't based on hype and jibberish....but rooted in facts and theories.
If you want a capper that is very selective in his plays he releases, then Essler fits that "bill". Dave will also in his write ups give you a few leans, ideas for other games, but not release them as plays. Many times I have used these ideas/leans to throw a few extra bucks on a game or parlay.
Great work Dave....keep up the hot streak.
