In the X-Men, Juggernaut was an irresistible, invulnerable helmeted villain who crashed through walls and overwhelmed any physical obstacle. Like Pete Johnson in 1981. But for our purposes here, a juggernaut doesn't need to be either villainous or ground-based. They just need to generate fantasy points. We're ranking NFL offenses 1 through 16. Later in the week, we'll sift through the dregs, 17 through 32, and look for anything useful.

Why go through this exercise? Because in the NFL, it's often the system that makes the fantasy stars. Alternately, a system can make even a supremely talented player irrelevant. Last season Cincinnati's second-leading receiver, T.J. Houshmandzadeh, outscored the combination of the Raiders top two wide receivers, Randy Moss and Ronald Curry. It wasn't really close, either. Houshmandzadeh totaled 155 fantasy points in a standard Yahoo! public league, while Moss and Curry combined for 137.

More Dilemmas: Picking at the Turn

Position runs are hypnotic. Like live interviews with Christian Slater or variety shows on Telemundo – even though you can't fully understand what's happening, they're almost irresistible.

Sometimes you really need to be an active participant. The opening rounds in most football drafts can basically be thought of as a position run. At least nine of the first ten picks are going to be running backs, and the second round will usually see another six or seven selected. You're not going to win a competitive league if you fail to involve yourself in the early RB binge. Sure, maybe this season an Ahman Green-Fred Taylor pairing can lead you to the playoffs, just like they did in 2003. Don't bet on it, though. It's not a position where you can wait for the third-tier and expect success.

But everyone knows that. The trickier position run begins with the first pick of the third round, when the wide receivers start going. Or rather, when the receivers who

These the three most exciting words in football:

"Grossman drops back!"

Wait, no. Those are the cruelest words. These are the three most exciting:

"Enter Live Draft."

They sit there on the screen, large and blue and inviting. Like Ben Coates used to look to Drew Bledsoe. After weeks of restless waiting, it's time. You've pre-ranked, you've mock-drafted. You've run that stupid Java test like 47 times.

You're ready. In fact, you're as ready for this as you've ever been for anything. Time to launch the applet. Is it possible that you're overconfident? No, not really. If you can back it up, it's not arrogance. You've participated in dozens of leagues. You've played all formats, owned basically everyone. There's no fantasy wrinkle you haven't considered. At this point in your fantasy career, you possess a kind of discursive wisdom that can really only …

Oh, (expletive).

The draft room just loaded. You're picking last.

In a default league, getting the last pick means you've got the 10th and
