MOVING TO FRONT FROM JANUARY 17: THE LIST GETS LONGER! COMMENTS ARE OPEN FOR MORE EXAMPLES
ANOTHER: Anthony Gonzalez, who was apparently a very good philosophy student at Ohio State (scroll down for a profile). (Thanks to Don Hubin for the pointer.)
AND ANOTHER: Lawrence Jackson, who had to switch from philosophy to sociology because all the philosophy classes were at the same time as football practice! (Thanks to Evan Goodwin for the pointer.)
AND STILL MORE: Philosopher Lani Roberts tells me her former student, Sean Canfield, graduated in philosophy from Oregon State and played for the New Orleans Saints. And Jonathan Hecht points me to tihs story about Vincent Brown (scroll down), who studied philosophy at San Diego State before heading to the NFL.
