odd, the links I provided had different #s. Do you have a link?

Subscription required. Not sure what methodology teamrankings.com uses that makes the end result different but KenPom.com is pretty much the go-to for CBB by broadcasters, coaches, writers, etc.
maybe my memory is jaded by the late season collapses the last couple years and hearing Fran saying they couldn't get stops down the stretch.
They've definitely had stretches where the defense falls apart. Last year was more the offense though. The only really bbad games were Indiana (x2), at PSU inexplicably and Villanova. The offense was a bigger culprit in the losses late.
'15, White's senior year, they were pretty good in the non-conference, horrible early in the Big Ten, then really good the last month or so until Gonzaga.
2014, Marble's senior year, they completely collapsed defensively in the last month which led to the meltdown.
2013, May's senior year, they were really good all year. They only had a couple horrible games all year at Va. Tech and Michigan. If that wasn't one of the worst 3P shooting teams in the country (or didn't get fucked against MSU), Fran would've had 4 straight NCAA's which has hardly ever happened here.
