Tom Izzo worried for four days about Michigan State's trip to Nebraska, and early in the second half it looked as though his concern was justified. The Cornhuskers, who can just about be counted on to upset a ranked opponent at home once a season, were within a point and had all the momentum. But No. 8 Michigan State's defense suddenly kicked in, forced misses on 10 of the Huskers' next 12 shots and the Spartans used a 20-6 run to break things open in a 73-64 victory Saturday night.
