Maybe it’s the fact I don’t sleep much any more, or that I seem to spend my entire life – outside of work – either shoveling snow or changing diapers. Maybe, my mind has been melted from seeing far too many early morning Shake Weight commercials that are creepier than Al Davis.

I don’t know what it is, but there’s just something about this NFL season that has me baffled.

Here’s a rundown of what’s happened so far: Two Super Bowl favorites, the Vikings and Cowboys, have a combined five wins, or in other words, the same amount of wins as Oakland, Seattle and Jacksonville. The N.Y. Jets, another Super Bowl favorite, lost its opening game, rattled off five straight wins, then needed overtime to beat both the Lions and Browns, and that’s after needing a pass-interference call to beat the Broncos. The Patriots looked to be the best team in the league – before losing to Cleveland. Then they came back and whooped the Steelers, another team people had pegged as a contender. The Giants looked to be dominant in the NFC, before getting blown out Sunday by the afore-mentioned (and pitiful) Cowboys. Philly has gone on a run to tie for the lead in its division after replacing QB-of-the-future Kevin Kolb with an ex-con, who hadn’t started a game in more than three seasons. Chicago’s winning; Cincinnati isn’t; and the Colts, Chargers and Titans can’t seem to get anything going. Oh yeah, and Kansas City is tied for the AFC West lead.

Get all that? Neither do I.

The one thing we can say with certainty about this season so far is that nothing makes much sense. There definitely is no true favorite, and you could make the case that about eight different teams are the best in the league.

I’m not even going to pretend I know what will happen down the stretch, but, in honor of all this chaos, here are some random thoughts from a random season.

Run ’til your tired. This much I know is true about the NFL – there’s no such thing as running up the score. For those who whined about Denver keeping its starters (and continuing to pass and challenge calls) late against K.C. Sunday, there’s always a solution to your team getting embarrassed: Play better. These are pros; it’s not one team’s fault if the other team doesn’t play like it.

The ol’ switcheroo. Although he seemed absolutely incapable of emotion while on the sideline, I’m sure Wade Phillips had to be fuming by watching the Cowboys suddenly decide to play hard and focused Sunday under interim head coach Jason Garrett. These guys are paid millions to go out and give an effort, but they need a longtime backup quarterback to put them in full pads for practice before they’re willing to show up? Huh, maybe Minnesota should hire Gus Frerotte after they fire Brad Childress.

Brady busts out. It was nice to see Tom Brady finally look like Tom Brady again, as he absolutely torched the Steelers. The guy’s got three titles, a handful of passing records, a super-model wife, a beautiful actress for a baby momma, millions of dollars – so, you know, it was nice to see something go right for him.

Ex-con, ex-underachiever. The best thing about Michael Vick’s resurgence is he’s, by all reports, putting in all the work necessary to be a top-level QB, and it’s definitely paying off. Some interesting comparisons to Steve Young have started coming up, and they seem warranted at the moment. Maybe, Vick can have that same late-career turnaround.

On the dotted line. Two weeks after being benched and playing like he may be nearing the end of his career, 33-year-old Donovan McNabb was given a new contract Monday by the Red Skins – for five years and a reported $78 million, comparable to his 75 QB rating. He’ll be 38 when the contract ends, and he already looks like he’s 48.

Maybe the ‘Skins know something we don’t. Maybe they expect him to retire before the deal ends. Maybe, like me, they need more sleep.
