Sam Webb does a very nice ARTICLE on Jabrill Peppers's background. Many of the general points are known (esp. re: Peppers's dad), but a very worthwhile read all the same. He discusses his commitment freestyle, as well as several deeper matters.
My favorite observation from Peppers re: Michigan's football program?
Michigan provided an ideal mix of all of those attributes, but there was one specific trait that allowed the Wolverines to distinguish themselves tangibly from their opposition. The ability of the players and coaches to connect with Peppers during his early April visit to Ann Arbor was summed up in one memorable statement.
"Real recognizes real," Peppers said afterward.
