ANN ARBOR -- Almost one month ago, some six weeks into the start of the regular season, Jim Harbaugh remarked about how he enjoyed sitting in on offensive line coach Ed Warinner's meetings.
Warinner, hired in January as an offensive analyst before being promoted offensive line coach, has impressed Harbaugh. And the Michigan head coach has made no bones about saying so.
The same could be said about Don Brown, Harbaugh's defensive coordinator who leads the nation's No. 1 defense. Ever since arriving at Michigan, Brown's defenses have finished at or near the top nationally.
While the results speak for itself, so does the animated, and at times loud, Brown.
