What's the Best Betting Value in the NCAA Tournament?

So, who will win the 2009 NCAA men's basketball tournament? I haven't a clue, but it will be one of 65 teams. I know, that's a great insight - you can thank me later. Looking at the initial odds posted by the Las Vegas Hilton (referenced in a story in the Las Vegas Sun), there may be some teams that based on the odds relative to their seeding, might be worth a gamble.

I took a look at the odds posted for the various teams and mapped them to their seeding. I averaged out the odds per seed level and looked for teams that the posted odds were significantly above the average. Before I give you the possible values, here's the average odds per seed level:

Seed Avg Odds

1. 5.75
2. 14.25
3. 28.75
4. 47.5
5. 71.25
6. 56.25
7. 100
8. 175
9. 250
10. 200
11. 475
12. 175
13. 400
14. 200
15. 200
16. 200

You can see that there is a natural trend that the lower the seed, the higher the odds, except for the lowest seeds. The LV Hilton sportsbook has most of the teams with discrete odds, with a field entry for everyone else. The field entry for this tournament consists of all 14-16 seeds, plus Northern Iowa and Akron. I don't think the field entry is a value bet, even though you get a chance on 14 teams.

Notice that the 5, 9 and 11 seeds on average pay more than the next lower seeds. We'll look there and also look at other seed levels to determine if a team or two is being offered at a significant differential to the average odds for the seed level.

If we set a level of differential to identify those teams whose odds are 75% higher than the average odds of their seed level, here's what we get:

4/Xavier - Odds 100:1/Seed Avg Odds 47.5:1
6/Marquette - Odds 100:1/Seed Avg Odds 56.25:1
9/Siena - Odds 500:1/Seed Avg Odds 250:1
11/Utah St - Odds 1,000:1/Seed Avg Odds 475:1
13/Cleveland St - Odds 1,000:1/Seed Avg Odds 400:1

If we lower the value threshold to 40% higher than the average odds of their seed level, these other teams appear:

5/Utah - Odds 100:1/Seed Avg Odds 71.25:1
5/Illinois - Odds 100:1/Seed Avg Odds 71.25:1
8/BYU - Odds 300:1/Seed Avg Odds 175:1
10/Minnesota - Odds 300:1/Seed Avg Odds 200:1
12/W. Kentucky - Odds 300:1/Seed Avg Odds 175:1

This will be interesting to see if any of these make a Cinderella run, or, if the oddsmakers are right, they make an earlier exit than expected.
