Adrian Peterson is going to make a lot of us look stupid. Maybe not quite as stupid as he made Andre Dyson, Jonathan Vilma and David Barrett look on Friday, but stupid nonetheless.

If you haven't yet seen Peterson's 43-yard run against the Jets, here's a link. I'm not sure how long the NFL typically allows copyrighted material to just sit out there, totally accessible. They seem to prefer burying it deep in the video catacombs of the league's website. So you'd better view that clip now.

It was obviously a well-blocked play. But the spin to shake Dyson, the sprint past Vilma, and the total obliteration of Barrett were all Peterson's doing. It's not a run that you're going to see from Chester Taylor. In fact, it's not a run you'll see from many of the 28 players ranked ahead of Peterson in the Yahoo! experts RB ratings.

Two games into the Vikings' preseason, I'm willing to officially declare that we blew this one – and the Yahoo! experts are hardly alone. A little benchmarking within the

Fantasy football, like any other vast institution that takes your money and destroys your self-worth, has its dogma. There's a system of shared beliefs in the fantasy community that's basically unchanging.

Most of these beliefs are totally solid, too. Some are maybe truer than others; we'll sift through them here throughout the preseason. But really, if you strictly obey the templatized draft tips and player rankings that you'll find in any fantasy guide, you'll give yourself a chance to be competitive. And you won't get badly mocked in the draft room.

You'll also miss a few things. If you're willing to be ridiculed in draft chat for reaching early on a player or position, you can really construct an excellent team, free of the sort of mid- to late-round veteran detritus – Ahman Green, Isaac Bruce, Joe Horn – that no one really wants to own. Or you might actually do something that deserves ridicule. Either way, you'll have taken a considered risk, which is more than most owners can

This is really a terrible time for a fantasy football draft. Rookies are unsigned, Larry Johnson is holding out, and important skill position players are ambiguously injured. But there's something so earnest about Chad Johnson's face in these ads. It's like every time you navigate away from the fantasy home page without registering a team, Chad hurts.

No one wants that. Except maybe DeAngelo Hall and every Steeler. So even though it's absurdly early, the Yahoo! Tank Johnson Desert Classic held its draft on Thursday night. This is, you might recall, a league full of sports bloggers. It's an indescribably funny group.

Literally, the funniness cannot be described. Right now there's an email exchange taking place between league members that's both amusing and almost entirely un-publishable. Here's a sampling …

There are all sorts of problems with experts-only fantasy leagues, but the biggest one is this: they're full of fantasy experts.

We're predictable and dull. We travel in herds, drifting toward the same sleepers, often using similar draft strategies. Like most herd animals, we also graze. And a few of us are picked off each year by large, predatory cats. Brad Evans was badly mangled by a snow leopard in 2005. Very sad, but he's a fighter.

Preseason experts drafts are useful tools, of course. But as we play out the leagues, not many extraordinary things happen. You won't see many drunken 4 a.m. add/drops. Experts don't vengefully cut elite players after bad games. You don't see message board posts that read like this:

What teh (expletive)?! That trade is a (expletive) JOKE!!! Everyone should V-I-T-O!!!

In short, experts leagues are almost inexpressibly dull. They're shrewdly played by people who've played for many years. Fantasy experts don't want to embarrass themselves, either. Message
