Michigan football planning 'greatest coaching clinic of all-time'

Apparently the newest weapon in the college football arms race is.... celebrity coaches?

After Jim Harbaugh made headlines with the Michigan football satellite tour last summer and a star-studded quarterbacks camp, his new plans were released on Twitter on Wednesday by staffer Chris Partridge.

Harbaugh and his staff will be joined by his brother, John, and the entire coaching staff of the Baltimore Ravens in March for the Wolverines' coaches clinic.

Has there ever been a greater coaching clinic? Perhaps that remains to be seen, but it is hard to deny the appeal of getting to work with not one but two coaches who have coached in the Super Bowl.

You can bet Urban Meyer is working on a way for Ohio State to counter this as we type this.
