Team 1 is Ohio and Team 2 is Michigan State.  Ohio SOS is 23rd in the country.  We start to hit some 200 and 300 rpi's in next two weeks so we will slide out of top 100 when that SOS soars. SOS will kill the rpi over the long run. We don't see anymore top 10 teams like Kansas again until March

We would be 3-5 if JG had one of Timmy's OCC schedules, because we've already established that Timmy had a much tougher one

Can anybody explain to me how Akron has an RPI of 32?

I cant really answer why the rating is that high, but their OOC schedule is MUCH better than it usually is, having already played Dayton & Cleveland State, and soon to play Temple, Minnesota, & Miami (FL).  That's 5 schools that people have actually heard of, which has to be a school record for them.

My question would be: why the disparity between Sagrin and RPI?

Sagrin ranks OHIO at #151 and SOS of #136 after last night.

Sagarin takes into account margin of victory and fully builds in home/road adjustment. Similar to the systems the folks in Vegas use so I prefer it over RPI. But RPI seems to be the record of reference when people talk strength of teams.

Thanks Ted...that logic makes snese and I guess that is why I like it as a "better" predictor of where we really are right now.  Hard for me to believe that either the Team or SOS is Top 50.  Other than Kansas (who kicked our butts), who have we played that would get us those kinds of rankings.  Is there a "marquis" win (yet...Temple to come!)?

I think RPI is record of reference often because the selection committee uses it (by looking at a team record vs. RPI top 50, top 100, etc.) when determining at-large bids.

I think Sagarin typically gives you a better picture, especially early in the season.  The sample size is still small enough, and scheduling oddities play a factor.  Also, Sagarin's ratings early in the year include a base rating of a team (a preseason rating) -- those are still in play at this date.  Sagarin rates us 87 with his ELO_Chess, which doesn't include point margin -- much closer to the RPI formula, while we rate 216 in the Predictor (which factors points heavily).  His overall rating is an average of those two pieces.

The two formulas tend to match up better the more data you put into them.

That's right.  It's interesting to see the degree of correlation between the Sagarins and RPI increase as the season progresses. 

Overall, I think Sagarin is the better indicator, though it can't be used by the NCAA tournament selection people because the Sagarins factor in margin of victory (though there are diminishing returns the greater the margin...e.g., the first 30 points of Kansas' margin over Ohio would be more statistically significant in Sagarin than the last 27 points).  Imagine if teams knew that margin of victory would be factored into at large selections and seeding.  It could get ugly.

What's ironic is that on the football side the BCS computer calculations aren't allowed to include the margin of victory component. But you know very well that humans are taking into account margin of victory when they place their vote in polls.
