John Thompson III won't have to make a name for himself at Georgetown. "Pops" took care of that long ago. Ready to take on the pressure of living up to the legacy of his Hall of Fame father, Thompson III was hired to coach the Hoyas back to national prominence.

The younger Thompson, 38, comes with a successful track record. He led Princeton to a 68-42 record over four seasons, including Ivy League titles and NCAA tournament berths in 2000-01 and 2003-04.
