Col, in the context of the article i think they simply meant that he had no shot since his whole family played on the other side of the ball:
"Two of Fox' uncles, Kenny Kuhn and Mark Stier, were Ohio State linebackers; another, Tim Fox, played defensive back for the Buckeyes and 11 years in the NFL. Dustin was a cornerback at Ohio State. Only big brother Derek shucked family convention. He played safety... at Penn State.
Carrying the football, you see, simply isn't done on either side of the Fox family tree."
