The MRI will determine Purdue's Final Four odds, so forget the RPI. At the moment, it's not important to Purdue.
The three letters that matter most now are MRI - as in the MRI that's expected to be conducted on Robbie Hummel's right knee Thursday, as in the MRI that'll likely have more to do with whether the Boilermakers make the Final Four than the seed or draw the NCAA tournament selection committee deals them.
Yes, this is that big.
Hummel is not a National Player of the Year candidate, nor is he Purdue's leading scorer. But he's a crucial part to what the Boilermakers do, and everything changed when he crumbled to the floor with a knee injury in the first half of Wednesday's win at Minnesota. How bad is the injury? There's still no official word. But it's worth noting that nobody connected to Purdue is suggesting it might be OK. In other words, everybody is holding out hope, but nobody seems hopeful, and that's probably not a good sign. At least it's not usually a good sign.
Either way, this is awful.
Hummel was averaging 15.8 points and 7.2 rebounds per game, and he had Purdue in position to win the Big Ten, earn a No. 1 seed in the NCAA tournament, and perhaps advance to the Final Four. All those things are still possible, of course. But the odds of any of them happening will decrease drastically if Hummel's MRI doesn't produce good results.
So again, forget the RPI; the MRI is all that matters now.
