It's a pretty impressive list for ol' KU, and even then it leaves out some notables in athletics who were stars in their day, including a few NFL players that I remember quite well.
Pittsburgh Steeler TE Larry Brown (1971-84; a stalwart with 4 SB rings and 3 Pro Bowl appearances; a member of the Steelers All-time Team)
LA Rams defensive back Leroy Irvin (4x All-Pro; with LA 1980-89).
Star NFLers not in the list from before my time?
Otto Schnellbacher AA 1947; all-pro DB with NY Giants
Oliver Spencer AA 1952; played OL for Green Bay and Detroit
George Mrkonic AA 1951; played OL with Philadelphia and in the CFL
Mike McCormack AA HM 1950; NFL HoF OL with Cleveland, called "finest offensive lineman I've ever coached" by Paul Brown;
NFL coach; helped establish the Carolina Panthers.
Galen Fiss KU: 1950-52; 2x AllPro LB (1962,63) with the Cleveland Browns, NFL champion 1964
