I am not very familar with Massey ranking
and latest RPI as of midnight yesterda

Massey is a mathematician who developed his system in the 1990s to evaluate any competitive league, and you can use his system for almost any pro or college sport. It predated things like RPI and NET and was partly an inspiration for them, but was always more sophisticated and---to its fans--more accurate. It is like all computer rating systems dependent on the amount of data that goes into it, and so it gets more accurate as the year goes on.
He gives a full explanation here:

Quote:Ratings Overview
In essence, each game "connects" two teams via an equation. As more games are played, eventually each team is connected to every other team through some chain of games. When this happens, the system of equations is coupled and a computer is necessary to solve them simultaneously.
The ratings are totally interdependent, so that a team's rating is affected by games in which it didn't even play. The solution therefore effectively depends on an infinite chain of opponents, opponents' opponents, opponents' opponents' opponents, etc. The final ratings represent a state of equilibrium in which each team's rating is exactly balanced by its good and bad performances.
Utah probably dropped because it was getting credit for wins over good opponents, who must have lost that day. For example, one of Utah's best wins was over 14 Arizona, but Arizona lost yesterday to a weaker Oregon State. Perhaps this, and other games, are what affected Utah.
Massey does take account of home and away games, so my guess is that we were weakened by our loss, but not enough to drop us below UConn with even more losses than we have. If we had lost at home, it might have been enough.
One of the interesting things about Massey is that his system generates offensive and defensive power ratings. Here, for example, are what they are today for a few teams:
Offensive Teams:
1 Iowa
2 Oklahoma
3 Utah
4 Maryland
5 South Carolina
6 DePaul
7 LSU
8 Ohio State
9 UConn
10 Florida State
11 Indiana
12 Stanford
Defensive Teams
1 South Carolina
2 Duke
3 Stanford
4 UConn
5 Princeton
6 Texas
7 USC
8 Mississippi
9 Indiana
10 Georgia
11 Colorado
12 Washington
Notice that Utah really is an elite offensive team and we are next in the league, but a ways back.
Notice that we really are an elite defensive team, but see that USC, Colorado, and even Washington are nationally ranked for defense too.
Utah is 80th in defensive rating, but that must be an improvement over last year.
