Popular coaching brothers Jim and John Harbaugh are trying to create the "Greatest Football Clinic Ever." In March, Jim's entire Michigan Wolverines staff and John's entire Baltimore Ravens staff will team up for three days to offer their insight to coaches across the country.

Detroit Lions defensive coordinator Teryl Austin was named one of the event's keynote speakers.

Austin will speak about the importance of defense. Similarly, the Harbaughs will have two other coaches serve as keynote speakers for the two other phases of the game. Former St. Louis Rams head coach Mike Martz will focus on offense, and former Virginia Tech head coach Frank Beamer will cover special teams.

In two seasons with the Lions, Austin has built a strong defense. After fielding the NFL's second-ranked defense in 2014 (300.9 yards against per game), his unit dropped to 18th in the league this past season (349.6 yards against per game). Part of the drop-off was due to the loss of two key defenders in tackle Ndamukong Suh and linebacker DeAndre Levy.
