My Ears Are Bleeding

It's always a mistake to take sports radio too seriously. But listening to Colin Cowherd is painful today.

He's assessing the line on the game and talking nonsense in every direction. He says that the Steelers are so clearly better than the Seahawks that the line should be eight points. He saying that Vegas thinks Seattle is better because everyone always bets the favorite and the favorites always cover. So why not a bigger number on the Steelers?

Where to begin? First of all the Steelers are not clearly better than the Seahawks. I have a pretty extensive objective analysis of how teams rank in the statistics that most correlate to winning and Seattle scores better than Pittsburgh. You can quibble with quality of opposition. That's a reasonable argument that could play in Pittsburgh's favor. But it's far from conclusive proof of anything. And I'll concede that Pittsburgh is No. 1 in my two most important categories: YPA Net and net points per pass attempt. But Seattle is solid across the board and ranks higher in net red zone possessions, a late entry to the Index but one that correlates nearly as strongly as the two stats previously cited.

I will not deny that betting psychology favors Pittsburgh and that Vegas factored that into the line. There are many more Steelers fans than Seahawks fans because so many front-running 35-year-old guys across America were in their underoos when the Steelers were last winning Super Bowls. Plus, the Steelers are the "team of destiny," which fools always back mid-story and are most often wrong about. That's why the line is out of whack here (it should be, at worst, a pick 'em on the numbers).

Secondly, not everyone bets the favorites just because they've covered 31 of 39 times. Lines stabalize when there is equal money on both teams. If there's not, the line keeps moving until the action evens out. Some argue that this might be the case in Vegas, but not necessarily on the street. That's true, of course, but, statistically, there is a very small chance that the betting tendencies in any community outside of the home cities varies significantly from what's going on in the legit gambling houses. In other words, if a four-point line evens out the action in Las Vegas, Nevada, it very, very likely does the same in Hoboken, NJ.

The game opened at 3.5. It's gone up to 4 in most places. That means that the line is pretty good. Again, most of the action will be placed in the coming days but statistically it's very unlikely to differ in ratios of Steelers and Seahawks money than what's been placed to date. And you don't need a math degree to be able to understand that, just an informal education on bookmaking and gambling from the streets (I got mine on the School of Union Avenue at the University of Paterson, NJ). Lesson one: bookies and casinos don't make their money by gambling. They want the tidy 10 percent on every bet, which they only get if the scales are in balance.

What's going on here is the thing that always happens in gambling. Everyone is a winner. All those people who bet on all those Super Bowls bet the favorites because the favorites won. And everyone who goes to Vegas or Atlantic City always wins a little. We're all so smart. Yet those casinos are so big.

Sloppy Analysis

It happens to all of us, but I'm less tolerant of analytical oversights when they are committed by major media outlets.

I'm getting ready to write my previews and I go over to the SI site to see if Dr. Z has filed yet. No dice. But I notice an article on how Super Bowl running backs have been a bust. The writer (Reuben Frank) notes that no running back has had a carry over 27 yards in a Super Bowl in 13 years. And then we're informed that no back has had a carry over 30 yards since Thurman Thomas against the Giants in 1991 (31 yards). It doesn't take very long to go through the memory banks of Super Bowl games and come up with a challenge. There was that great TD run by DeShaun Foster against New England a couple of years ago. I assume that was under 27 yards because there's no way the writers AND the editors would miss something so obvious. Remember, they're not even talking TD runs here; but all runs. It's much harder to overlook a scoring run. Nonetheless, I could swear that was over 30 yards. I look it up and sure enough it was 33. Now why should I bother reading anything else that guy writes?

Setting aside the mistake, I don't understand what Frank is so amazed about by the lack of long runs in Super Bowls. Runs of over 27 yards are relatively rare and the years we're talking about consist of one game. Edgerrin James went almost two years (~30 games) without a run over 20 yards and that was against everyone; these backs are usually going up against top defenses.

I will be curious to see if there's a prop bet for a run over X-number of yards for either back. If there is, it might pay to take the odds on a long run because this streak, even if it were true, is really not that impressive.
