I think for most of the season LSU was passing the eye test and I could understand the high ranking. They have some very big wins over good (not great) teams. But the last two weeks their schedule has gotten harder and their results have been notably worse.Good analysis of LSU’s weak schedule. Advanced metrics, which try to adjust for strength of schedule, also really like LSU. Their Her Hoop Stats (HHS) offensive rating, which is an estimate of the offensive efficiency (points scored per 100 possessions) they would have against the average D-I defense, places them 6th in the country (Iowa is 3rd). Their similar HHS defensive rating places them 4th in the country (Iowa is improved but considerably lower). Their net HHS rating places them 4th in the country (Iowa is 7th).
Schedule is something I've thought about more lately. Back to my Nebraska example, Iowa recently had a stretch at Ohio State, vs. Nebraska, and vs. Maryland. Nebraska was clearly the third best team in that stretch.
For most of LSU's schedule, they've faced a team like Nebraska, but the surrounding games have been against weak opponents. I think it's easier to win those games for LSU than it is for Iowa when Nebraska is the weakest opponent in a 3 game stretch. Now LSU is playing a few teams similar to Nebraska in a row and it isn't doing as well.
LSU could well be a 1 or 2 seed on talent. But I don't think we know that yet. And we do know that South Carolina and UConn are, and Stanford is most games. That's why I'd take my chances with LSU.
