I believe Rip Engle is in the HOF.
PSU has 6 former Head Coaches in CFB HoF:
Bill Hollenbach (1909, 1911-1914), 28-9-4 .732 (PSU has a claim to both the 1911 and 1912 National Championships)
Dick Harlow (1915-1917) 20-8-0 .714
Hugo Bezdek (1918-1929) 60-30-11 .665
Bob Higgins (1930-1948) 91-57-11 .610
Rip Engle (1950-1965) 104-48-4 .680
Joe Paterno (1966-2011) 409-136-3 .750
Those who claim that PSU was not a National Profile program prior to JVP are full of it (Brown was a top 10 program when Rip Engle left there for PSU in 1950 - immediately offering his just graduated QB an Asst job). PSU played in the 1923 Rose Bowl under Hugo Bezdek.
