17. Marshall Faulk
No. of kids / No. of baby mamas: 6 / 3
Marshall ran up a lot of things in his heyday. He rushed for over over 12,000 yards and scored 100 rushing touchdowns when playing for the Rams and the Colts, but the recent Hall of Fame inductee (2011) also ran up in his share of women. He fathered six kids with three different ladies. Run Marshall, run!
