I'll just go on record: I hate this week's picks. Lots of favorites (which I'm not a fan of), almost no home dogs, lots of away teams... the worst of the worst of the worst. I'm expecting a huge down week. But I go where the stats take me. Sigh.

The power ranks seem to be working though. StL shoots up this week. Still have to test it's validity, but... fun?

Week 03: Historical retrospective

Historical win percentages by pick rank back to 2006 under the current model for spread and moneyline bets - not the moneyline win percentages are misleading, since the model favors lower probability wins to high payout ratios rather than "straight up" winners. When gambling, the straight up favorites are usually the sucker's bet - who wants to lay a fiver to win 76 cents on a -650 high probability winner? In fact, the exact probability (according to Vegas) of a -650 covering is 81.59%. That's a whopping 19% chance that you WON'T win that 76 cents - you keep that bet up over time, and you're out 6 cents on every dollar you bet - not a lot, but enough to make it not worth it. (If you're interested, the math for this is simple - 80% of the time, you win 76 cents, and 20% of the time, you lose 5 dollars - so [.8 x .76] + [.2 x -5] = -.39 cents divided by 5 dollars = ~-7 cents per dollar).

Bearing that in mind, here you go - spread than money:

Week 03: Altered power ranks, liking the bets this week

First, the bets. Here are the spread picks:

Rank Pick Vs Spd Bet % Bet Amt W/L Payout
1 KC v. SF +2.5 7% $5.78
2 ATL @ NO +4 7% $5.72
3 NYJ @ MIA +1.5 7% $5.67
4 SEA v. SD +5.5 7% $5.61
5 TB v. PIT +2.5 7% $5.56
6 CIN @ CAR -3 7% $5.50
7 OAK @ ARI +4 7% $5.44
8 TEN @ NYG +3 7% $5.39
9 DET @ MIN +10.5 7% $5.33
10 STL v. WAS +3.5 7% $5.28
11 CLE @ BAL +10.5 6% $5.22
12 DEN v. IND +6 6% $5.17
13 DAL @ HOU +3 6% $5.11
14 PHI @ JAC -3 6% $5.06
15 NE v. BUF -14 6% $5.00
And the moneyline:

Rank Pick Vs ML Bet % Bet Amt W/L Payout
1 KC v. SF +120 7% $5.00
2 TB v. PIT +120 7% $5.00
3 DAL @ HOU +120 7% $5.00
4 TEN @ NYG +140 7% $5.00
5 ATL @ NO +175 7% $5.00
6 OAK @ ARI +175 7% $5.00
7 STL v. WAS +170 7% $5.00
8 SEA v. SD +210 7% $5.00
9 DET @ MIN +425 7% $5.00
10 CLE @ BAL +425 7% $5.00
11 NE v. BUF -900 7% $5.00
12 IND @ DEN -260 7% $5.00
13 CIN @ CAR -190 7% $5.00
14 PHI @ JAC -145 7% $5.00
Notice the new trend in the moneyline bets - I changed the formula, I'm now calculating it based on probabilities. It places more emphasis on high win potential games based on payout and probability. It's a tricky formula, maybe I'll go into it in a later post.

For now, I've altered the power rankings back to their original design of estimating team performance against the spread (rather than "who's the best team"). It now deviates substantially from my inspirational source of data, Football Outsiders. And it appears to work - over the last 4 years, the top quartile teams by week 17 had substantially improved ATS records over the rest of the teams. The motion in the teams is NOT effected by whether or not they covered in the previous week (or even whether they cover at all!), it's instead based on spread conviction and expected performance in games week to week. So it's a true predictive ranking rather than descriptive of past ATS records. Very cool.

Here it is:
