New chart for showing projected records

I had an aha moment today with an idea of how to visually display the projected record my computer has for NFL teams.  For each team, I calculate the chances of each possible record, and then list the most likely record as the projected record along with the chance of finishing one game better or worse.

But that doesn't tell the whole story.  If you graph an individual teams possible projected records, you get something of a bell curve with the most likely record in the middle.  But it would be a pain to have 32 different charts to have to look at, so I've come up with a way to display all for a given conference on a single chart.

It is a little overwhelming at first, but take a look at this and let me know what you think.

What this is showing is a segment for each team for each possible win total indicating the likelihood of that record.  The size of the segment indicates a higher likelihood.

So for example, Atlanta in blue has a small chance of going 15-1 and a smaller chance of 10-6, the most likely record in between being 13-3.  Then Chicago is in red, the 49ers in orange/yellow, etc.

I used a stack bar chart to be able to fit it all on a single chart so it is a little complex, but I think it is somewhat useful.  Let me know what you think.

Oh, and the above is showing the current projected records after the Sunday night game.

Will we have a BCS title game between undefeated teams? Or can the SEC find their way back in?

With Alabama's loss, we are down to 3 undefeated teams vying for participating in the BCS title game; Oregon, Kansas State, and Notre Dame.  There are only a few games left, so there is a good chance 2 will stay that way, but what are the exact chances of that occurring?

The 3 teams in question have the following chances of finishing perfect:
  • Oregon - 81.7%
  • Kansas State - 78.7%
  • Notre Dame - 37.8%
It is safe to assume that any 2 undefeated results in them facing each other.  It is also probably safe to assume that if Oregon and K-State do it, Notre Dame gets left out.

So, there is a 64.3% chance of Oregon and Kansas meeting as undefeated teams.  But if one of them falters, Notre Dame could fill in.  Running the different permutations results in a 75.7% chance of some combination of these teams facing each other as undefeated teams.

If you look at that number, there is a good gap between it and 100%.  So what happens then?  It is probable that should the SEC champ finish with 1-loss, they would be the choice if 2 of the aforementioned teams have a loss.  So what are the chances of a 1-loss SEC champ?

Alabama has the best chance at 70.4%, but Georgia has a 27.5% chance too, and should Georgia falter and let Florida in the title game, they have a 20% chance.  If we put these permutations together, we have a 99.2% chance of a 1-loss SEC champ.

That means that there is still a 24.1% chance of an SEC team making it to the BCS title game.  Trust me, stranger things have happened.

College Football Week 11 Season Projections - Only 2 projected to be undefeated

The projected records for the regular season using results through week 11 are now available.  These projections now include projected conference championship games.

And then there were 2!  With Alabama's loss, and Notre Dame rating dropping a bit, just Oregon and Kansas State are projected to finish the season undefeated.  And both teams are definitely projected to do so at 82% and 79%.  This puts the chances of both occurring at 64% so a very good chance we have a match up of undefeated teams in the BCS Championship game.

Notre Dame still has a chance at a perfect season at 36%, but a 1-loss season is more likely at 64% due to having to visit USC.

Ohio State actually has a better shot at an undefeated season at 38%, but the computer still says 11-1 is more likely at 51%.

Analyzing the 11/11/12 AP Poll - Alabama drops to #3 but ahead of Notre Dame on one ballot

Here is week 11 of analyzing the AP poll.  Thanks as always to the AP publishing their voting.

All 11 charts are displayed below to make it easy to see the changes.

With Alabama losing, there are some changes.  Oregon is up to #1 and receives only 1st and 2nd place votes.  Kansas State at #2 receives 1st thru 3rd place votes, and Notre Dame gets a 1st place vote but also two 4th place votes.  One voter has Alabama ahead of them, and one has Ohio State.  Note my computer agrees Notre Dame is too high, but voters don't always vote like they should :)

Florida is the first team that has varying opinions being votes everywhere from 4th to 18th.  Oregon State also has a bit of a range from 12th to 25th.




























College Football Week 11 Ratings and Rankings - Oregon remains #1, Alabama only drops to #3

This week's ratings and rankings are now posted.

This week's #1 is the same in Oregon, but there are some changes behind them.  Kansas State moves to up #2 replacing Alabama, but the Crimson Tide, while losing over 4 ratings points, only falls to #3 because of the big lead in ratings points they had.  Oklahoma was supposed to beat Baylor by more than 8 at home and as a result drops 2 spots to #6 allowing Florida, despite losing ratings points, and Texas A&M, to move ahead of them.

Notre Dame, who my computer has never really liked, has a closer than expected game, even with the lower expectations, with Boston College and loses ratings points and falls to #8.

The BCS compatible algorithm ratings and rankings have some changes too with Notre Dame falling from #1 to #3 simply because they played a weak opponent.  This is a clear example of how the rules the BCS has for the computers aren't exactly fair as regardless of the score, Notre Dame was in a lose lose situation by having to play a weak opponent.  The result is K-State is up to #1 and even Florida moves ahead of ND to #2 because their close win, the margin of victory doesn't count with this algorithm, was against a stronger opponent than Notre Dame's, didn't hurt them as much.

Oregon does move up to #4 in the BCS algorithm ahead of Alabama based on the loss.  Oregon will be helped in coming weeks by finally playing some stronger opponents.  And thanks to Alabama losing, may not be in the position of being left out of the BCS picture like they were last week.

The top-25 is below, full ratings on the site.

Estimated Dynamic NTRP Reports for Teams

I've been doing Estimated Dynamic NTRP Reports for individuals, but have had a few requests to do them for teams too.  If you have a team or group you want reports for, contact me and I can give a healthy discount over purchasing the reports individually.
