1. Purdue (23-2, 12-0 Big Ten)
The Boilermakers keep winning — 19 in a row heading into this week — but the past four victories have come by four, seven, eight and two points. Now, Purdue hosts Ohio State before playing at Michigan State in a span of four days. Fun for everybody watching. Maybe not so fun for coach Matt Painter to prepare for.
2. Michigan State (22-3, 10-2)
Had to rally from down double digits to beat Penn State at home, then held off a charge from Indiana to win by three in Bloomington.
