Right or wrong, Jim Harbaugh has tried his best to run the Michigan football program under a cloak of secrecy since taking the job at the end of 2014.
Last season, U-M was one of the few teams not to release a depth chart all year (recall Colorado's mocking of U-M with a fake depth chart starting Elmer Fudd at quarterback and Eric Cartman at left tackle), presumably to gain the slightest competitive advantage it could -- too bad that didn't seem to help U-M when it lost three of its final four games by a total of five points.
