N.B. This is speculation not a done deal.
11.30 | Dave Brandon said Tuesday he didn't want to host a night game "for the sake of a night game," which, reading between the lines, may mean Michigan Stadium's next evening tilt will wait some time. Next season doesn't appear to have a great opponent draw for a night game with Air Force, UMass and Illinois at home, followed by the annual in-state rivalry game against Michigan State on Oct. 20. Brandon has said he does not want to host a Michigan-Michigan State night game because it has the potential for crowd problems. ... A better bet or a night game will come the following season when Michigan plays Notre Dame on Sept. 7 at Michigan Stadium in 2013.
