A day that started with an altercation with Michigan State teammate Branden Dawson ended with a career performance for Adreian Payne. In between, there were some tense moments for the scuffling Spartans with an unhappy coach Tom Izzo and 20-plus minutes spent on the bench as punishment before Michigan State asserted control in the second half. Payne had a career-best 20 points in the 18th-ranked Spartans' 81-72 win Wednesday night, then paired with Dawson to share responsibility for their spat in Happy Valley.
