Digging Through the One Loss Teams

Right now, there are a mess of contenders
with one loss. I decided to apply the OTFRR
methodology to see how the teams measure
up. Let's see how everyone has done in W/L
compared to what we'd expect a #5 team to
do verse their respective schedules.

OTFRR#5 (Methodology)
Ohio State + 1.065 Expected 8.935 W 0.893 Winp
Kansas + 0.797 Expected 8.203 W 0.911 Winp
LSU + 0.662 Expected 7.338 W 0.815 Winp
Oregon + 0.469 Expected 7.531 W 0.837 Winp
Mizzou + 0.404 Expected 7.596 W 0.844 Winp
Arizona State + 0.318 Expected 7.682 W 0.854 Winp
West Virginia + 0.036 Expected 7.964 W 0.885 Winp
Oklahoma -0.013 Expected 8.013 W 0.890 Winp
Boston College -0.146 Expected 8.146 W 0.905 Winp

Digging through, the schedule strength from
easiest to hardest goes as follows:
Kansas
Boston College
Ohio State
Oklahoma
West Virginia
Arizona State
Mizzou
Oregon
LSU

As most college football experts hypothesize,
LSU and Oregon are the class of one-loss
teams. However, Mizzou is going under the
radar and should be getting some more
pub. They've looked impressive in a points
evaluations as well, which isn't considered
here. With Kansas and a potential BigXII
title game, Mizzou can make a major jump
in reality as well as in this evaluation tool.

I don't think Oregon can pass LSU if they
both run out the season due to LSU's lead
right now and the additional SEC title
game. But, alot can change. The SEC has
many intersectional games left that can
cause a change in how the LSU opponents
look at season's end.

Sorry UConn fans that I didn't consider you.
If your team wins next week, I'll have to add
in an evaluation.

Kansas Remains #1! Post Week 9

Methodology for ranking system. Rankings
are on-the-field win-loss results based.

So, another Saturday is in the books and it's
time to update the ratings. What follows is
the OTFRR#5 through Saturday, October
27th. The top 4 did not shift at all after all of
them surprisingly won their games, most in
dominating #1 fashion. The big news is that
Oregon has caught upto LSU among one loss
teams. Look for a post on the one-loss teams
coming up in the next few days.

Here are the rankings compared to a #5 team
Kansas +1.005W
Ohio State +0.887W
Arizona State +0.844W
Boston College +0.774W
Oregon +0.210W
LSU +0.204W

Kansas is over a full game ahead of what a
typical #5 team would be playing their
schedule. That's right-Kansas could've lost
a game this season and still had a top5 resume.

Oregon has played the toughest schedule so far
for the top 6 teams, but is essentially tied with
LSU for that honor. BC and Ohio State have
played the weakest schedules of the six teams
profiled here.

Expected #5 team performance for team schedules:
Oregon 6.790W 1.210L 0.8488winp
LSU 6.796W 1.204L 0.8495winp
Kansas 6.995W 1.005L 0.874winp
Arizona State 7.156W 0.844L 0.895winp
Ohio State 8.113W 0.887L 0.901winp
Boston College 7.226W 0.774L 0.903winp

Despite what the talking heads on tv say,
there are teams earning it on the field. The
tv pundits prefer to ignore it because it is
not the 'best' teams that are showing it on
the field. Sorry, it's not the 'best' team that
wins, it's the team with the best results.

Right now, I'd guess that Kansas and
Arizona State are the teams in control of
their destiny according to this ranking
system with BC a close third and Ohio
State a distant fourth.

Ohio State

One Week Makes a Big Difference

Heading into this week's games, I want to use
the 4 undefeateds to highlight how big real
conference contests are at demonstrating who
are the best teams in the country.

Going into this week, we have four undefeateds
in the BCS conferences.
According to the OTFRR#5, here are the wins
ahead of a #5 team playing their schedule and
the chance a #5 team would be undefeated
right now having played those respective
schedules.
Kansas +0.703 0.4219
Ohio State +0.659 0.4872
Arizona State +0.619 0.5185
Boston College +0.461 0.6047

Now, assuming those teams all win and
using the post week 8 sagarin predictors,
we'd have the following:
Ohio State +0.951W 0.3452
Kansas +0.894W 0.3413
Arizona State +0.821W 0.4139
Boston College +0.663W 0.4828

There are quite a few things I want to
highlight from this exercise. One, notice
how each team's chances of being
undefeated are now below to way below
50% even assuming they were a #5 team.
Along with this, notice how the top teams
are nearly a full win above what one
would expect a top 5 team to be. That
means that even with one loss, they'd
almost be right on the pace of a top 5
team playing their schedule.

Secondly, the potential week 9 
numbers show Ohio St jumping Kansas
even though Kansas still has the least
chance of being undefeated. In this case,
it shows how the depth of opponents
and more games can overweigh verse a
schedule that has a few more really
tough games.

Finally, the chart lends to the argument
that perhaps the voters have gotten it
right all this time in putting undefeated
teams into the title game ahead of very
talented one loss teams. It appears that
even the softest of BCS conference
schedules separates the wheat from the
chaff.

Kansas is #1! (post week 8 NCAAF musings)

Here's an interesting stat result about the 'top'
teams in the land:
Kansas +0.703
Ohio State +0.659
Arizona State +0.619
Boston College +0.461
LSU +0.376
Oregon -0.119

In my results oriented world, Kansas is the top
team in all the land. What are those numbers?
How did I get them? Well, I'll introduce that in
the rest of this post.

These are a pure results oriented ranking.  
They represent how many more (or less) wins
each respective team has verse the schedule
they played than a generic #5 team in the
land would have. That's the general idea and,
of course, it requires some breaking down as
there are quite a few assumptions
(reasonable I hope) and explanations.  

1) For each team, I gathered their opponents' 
sagarin predictor rating after week 8
Saturday games. Sagarin predictor is the best
known computer evaluation system and the
most reliable from everything I've seen. (In
an ideal world, I'd probably find a weighted
combination of all rankings, like on Massey
compare web page, and assign a rating
through that.)  

2) I then pull out the rating for the #5 team according to sagarin predictor

3) I construct a ex post facto 'spread' for
each game by taking the difference
between the #5 ranking and each
opponent's sagarin predictor and add or
subtract a blanket 3 point home-field
advantage.

4) From there, I convert the 'spread' into
a win pct by comparing
the 'spread' to the a database that has the 
actual win pcts for
each game played at that spread in college
football from 1993 to 2006 (ty to goldsheet
for that info).

5) After obtaining a win pct for a generic
#5 team against each team on the schedule,
I just add simple math to get the average
amount of wins the #5 team should have
against that schedule.

6) I then subtract the projected #5 team
win total from the actual win total for the
specific team to obtain a result for how
many wins a team has outperformed a
generic #5 team.

7) For giggles, I go further and work through
every possible combination to see what
would a generic #5's teams win total look
like against that schedule for all possible
outcomes.

Without further ado, here is some of the
grunt work for each team

Now, don't get me wrong LSU fans.  I do believe you might have the 'best' team. In no sport, however, is the title given to the 'best' team. It's given to the team that earns it on the field. While I don't think Kansas is as good as any of the teams I compared them against here. They've had the best results on the field. But, there are alot of games left and plenty of time for things to change.

BTW-I think LSU has had the toughest schedule and my analysis bears backs that notion. The key is the expected win pct for a #5 team playing the respective schedules.
LSU 0.828
Oregon 0.874
Kansas 0.900
Arizona State 0.912
Ohio State 0.918
Boston College 0.934


I might due some sensitivity analysis and see how the numbers come out if I go with the #1 sagarin predictor instead of #5.
