Assessing Ken Pomeroy’s Pac-12 Ratings

Posted by Andrew Murawa on October 31st, 2014

There once was a time, back in the day, when college basketball fans would eagerly anticipate the initial AP Poll as a harbinger of the coming season. Or maybe you were the kind of fan who took the Street & Smith’s magazine appearing at your local newsstand as the sign from the basketball gods that it was time to dig into the impending season. Nowadays, Street & Smith’s preseason magazines are long gone. The AP Poll may as well be. But with the rise of advanced metrics, college hoops junkies with a love for statistics can bask in the unveiling of Ken Pomeroy’s preseason ratings with the same joy that those old print-era milestones used to impart.

The personnel portion is looking at who is returning from last season’s roster, how much the returnees played, what kind of role each returnee had, and what class they are in.”

“The system does not give any special consideration to new players entering the program. There is some credit given for high-profile recruits, but the poor performances in 2012-13 of UCLA and Kentucky, among others, in recent years have tended to mute the impact of recruits in the model.”
