I know it's a long shot, but Mike Munchak, former HC on the Tennessee Titans, said he will interview for the opening at PSU. From an ESPN article:
"Sources say Munchak has a plan to adapt quickly to the college game in all operations, including a recruiting blueprint.
If Penn State and Munchak go in another direction, sources say the Pro Football Hall of Fame guard will entertain offers as an offensive line coach, where he built a reputation as one of the NFL's best position coaches."
I know it is referring to an NFL Line Coach, but to get an former Penn St star, NFL HC, and Line coach on to fill the void at Maryland, and in the Big 10, would be a big grab.
