Week 3 Rankings



Hey football fans!

Week 3 brought us our biggest match-up of the season so far in Alabama’s 49 – 42 victory over Texas A&M in College Station. Meanwhile, Oregon continued their early season domination with a 59 – 14 win over Tennessee, while UCLA and Arizona State made me look like a profit by defeating Big 10 foes Nebraska and Wisconsin, respectively. Unfortunately, Arizona State’s victory is marred in controversy thanks to the less than stellar officiating of the Pac 12 officiating crew.

Here are the updated top 10 after week 3:

The big story here is Oregon, who is now almost eight points better than the next best team in the country, Florida State. The Ducks probably aren’t that good but this illustrates just how dominant they’ve been in the first three weeks of the season. Otherwise, the top 10 is very similar to last week with only Oklahoma State and Ole Miss jumping into the top 10 to replace Stanford and Michigan, who both posted closer than expected wins over weak opponents in week 3.

Here are the top 10 teams with the best chance of finishing undefeated:

Oregon currently has an incredible 73% chance of finishing undefeated. This is almost certainly an overestimate but illustrates that they will be heavy favorites in every game for the rest of the season. Elsewhere, Louisville, Florida State and Alabama are all in great shape and there is a substantial drop from Alabama (38% chance of finishing undefeated) to the next most likely team to finish undefeated (Oklahoma State – 13% chance of finishing undefeated).

This weekend’s headliner is Arizona State vs. Stanford. Most would be surprised to hear that I have Arizona State (#18) ranked ahead of Stanford (#22) but Stanford is still favored because the game is at Stanford. Otherwise, this weekend’s slate is pretty lean but there are a couple other interesting games, if you look for them:

  • #18 (in my rankings) Arizona State @ #22 Stanford, Stanford favored by 2.2, 57% chance of winning
  •  #37 Tennessee @  #19 Florida, Florida favored by 9.6, 79% chance of winning
  •  #38 Michigan State @ #36 Notre Dame, Notre Dame favored by 4.2, 64% chance of winning

Week 2 Rankings


Hey football fans! Week 2 is in the books and we’re already seeing some big wins and upsets that will shape the season.
                     
Here are a couple of major results from week 2, in case you missed them: 
  • @ Georgia over South Carolina: 41 – 30
  • @Michigan over Notre Dame: 41 – 30
  • @Miami over Florida: 21 – 16
  • @BYU over Texas: 40 - 21
Georgia may have saved their season with a big win over South Carolina and Michigan established themselves as the team to beat in the Big 10 with a big win over Notre Dame. Meanwhile, Miami and BYU pulled big upsets over the weekend, resulting in major disappointment in Gainesville and Austin.

Here are the updated top 10 after week 2:

The top 5 were pretty stable from last week with only Texas taking a major tumble after their upset loss to BYU. In contrast, there was a lot of movement from 6 – 10 but that should settle down over the next couple of weeks.

Here are the top 10 teams with the best chance of finishing undefeated:

There are now three, distinct tiers in rankings by probability of finishing undefeated. Louisville and Oregon have greater than a 40% chance of finishing undefeated, Alabama and Florida State have about a 25% chance of finishing undefeated and we observe a steady decline in probability of finishing undefeated from #5 to #10. These probabilities are probably a little high due to early season volatility but I think the ordering provides a useful measure of the relative chance of finishing undefeated among the top teams.

There are several interesting games on the schedule this weekend, with the big rematch in College Station taking the headlines. Here’s a little more info on that game, plus a few more worth watching:
  • #2 (in my rankings) Alabama @ #15 Texas A&M, Alabama favored by 7.4, 71% chance of winning
  • #22 Tennessee @  #1 Oregon, Oregon favored by 21.3, 95% chance of winning
  • #21 UCLA @ #36 Nebraska, UCLA favored by 1.7, 55% chance of winning
  • #14 Wisconsin @ #17 Arizona State, Arizona State favored by 2.0, 56% chance of winning
