I like PPR because it rewards a skillful, well prepared player, plus it at least tries to acknowledge the tremendous real life value of receptions. But I don't mind playing touchdowns leagues because it keeps the pure running back and big play receiver viable, potent plays. I think it actually opens up the league by making more types of W/R available.
That said, what I don't understand is why anyone still does snake drafts instead of auctions? Drafts are such an inferior format. They reward stupid luck even more. You're set if you get a top pick and screwed if you get stuck in the middle. You lose the league on draft day because you were unfortunate to draw the 7th pick out of a hat. The auction format is better in every way. It definitely rewards skill because everyone has a chance at every player. It's a thousand times more engaging because you get to be involved in the picking of every player. It's far more dynamic and unpredictable, and therefore, more fun. Bidding adds an element of poker/psychology to it. And it's FANTASTIC to do with your friends. Unless you've done it before, you don't know how much fun it is to precipitate bidding wars between your friends for players you know they desperately want that you don't even care about. You haven't truly loved fantasy until you've gotten your buddy to pay 70 dollars for Adrian Peterson.
My family league STILL does a snake draft every year and it frustrates me to no end. I've pushed for an auction every year but the family is set in their ways and they're intimidated by the change. It sucks because this is the only league I care about winning, and the only league I put money on.
Also, I think keeper leagues are total bull**** too. It's for people who want to haze new owners and/or aren't confident enough in their own skill to win a fair competition. Needed to get that off my chest.
