The Michigan football coach took to social media, using a few brazen strokes of the keyboard Friday night to let everyone know what he thought about the so-called roster controversy that has sparked discussion over merit and Harbaugh's dome of secrecy around Schembechler Hall.

Harbaugh posted to Twitter a photo of the 1973 school roster from his old stomping grounds, Ann Arbor's St. Francis Assisi, unedited and in its original form.

It was all perfectly crafted (minus the incorrect spelling of "principal"); timely, witty and without regard to boundaries, media and his opponents be damned, a hallmark of Harbaugh's tenure at Michigan.

A check early Monday of the University of Michigan athletic department's website lists the 2016 team, including all 11 NFL draft selections and transfers who moved on to other football programs.

Since arriving in Ann Arbor in late 2014, Harbaugh has slowly peeled back the information provided for public consumption, from not supplying a list of dressed players on gamedays to being coy with injuries and suspensions, to being the only team in the country to withhold a depth chart in 2016.
