There was only one game between power-conference schools on Friday — Purdue at Michigan State. And things started well for Tom Izzo's Spartans. They led by 17 points with less than 19 minutes remaining and seemed on their way to extending their winning streak to three games. But Purdue closed on what amounted to a 39-21 run to edge Michigan State 55-54 inside the Breslin Center. So now the Spartans are 8-4 overall, just 2-4 in the Big Ten, and very much at risk of missing the NCAA Tournament for the first time since 1997.

"One of the more disappointing losses," said Izzo, who has guided the Spartans to 22 straight NCAA Tournament appearances.

That's the third-longest streak in Division I men's basketball, by the way. Only Duke and Kansas have been to more consecutive NCAA Tournaments. But with every loss, especially every loss at home, it's becoming increasingly likely that the Spartans will end up on the wrong side of the bubble come March. They're now 0-3 in Quadrant-1 opportunities and all the way down to No. 86 in the NCAA's latest NET rankings. For what it's worth, KenPom currently projects Michigan State to finish 8-12 in the Big Ten, meaning Izzo will end up with his first losing league record in 26 years as a head coach unless the Spartans outperform those expectations.

Michigan State has been removed from Saturday morning's updated CBS Sports Top 25 And 1 daily college basketball rankings. The Spartans were replaced by Colorado, which is 8-3 with wins over Oregon and USC heading into Monday's scheduled game at Utah.
