Two questions emerge from the A-C-C, Big Ten Challenge — is this a down year for the Big Ten and can anyone in the conference challenge Michigan State. The Spartans’ dominating 81-63 win over Notre Dame Thursday gave the Big Ten just three wins in 14 games. Coach Tom Izzo’s team emerged looking pretty impressive. The Spartans rolled past North Carolina and even out-rebounded Notre Dame 42-21. The Wisconsin Badgers open conference play tomorrow (Saturday) when they host Ohio State.
