INDIANAPOLIS -- So what to make of this stunning upset? Has Michigan State finally discovered something, or is Purdue headed for a fall in the NCAA tournament?

Who knows? But for now, the significance of Michigan State's dominant 74-56 victory over Purdue is clear: The seventh-seeded Spartans have earned a spot in the NCAA tournament.

What other conclusion could be drawn, given that ESPN bracketologist Joe Lunardi had Michigan State (19-13) as the "last team in" before tipoff? Beating the nation's ninth-ranked team should count for something.

Kalin Lucas was outstanding for the Spartans, who led the entire game and advanced to play the Penn State-Wisconsin winner on Saturday in the Big Ten tournament semifinals. Lucas scored 30 points and committed just two turnovers, despite relentless pressure from Purdue's guards.

Senior Kalin Lucas has been outstanding, scoring 18 points on 7-for-10 shooting - including 4-for-4 from 3-point land. Draymond Green has contributed with four points and seven rebounds.

Purdue, the Big Ten's No. 2 seed, is shooting 9-for-26 (34.6 percent) and E'Twaun Moore has just four points on 2-for-7 shooting.

The Boilermakers have made 1 of 10 3-point tries, compared with the Spartans' 7-for-9.
