The Clemson Tigers shook the college football world this week with the announcement of their new defensive coordinator being hired from one of the best units in the country. Clemson made things official on Tuesday with former Indiana Hoosiers head coach and Penn State Nittany Lions defensive architect Tom Allen to take over the Tigers defense and replace the fired Wes Goodwin.

Tom Allen served as Penn State's defensive coordinator for one year. He will reportedly be the fourth defensive coordinator hired under Dabo Swinney.
