Chuck Foreman was a fullback most of his career. However, Vikings gamebooks didn't specify it like some other teams. Bud Grant talked about it and so did Foreman.The Mercury News, Daniel Brown, January 2016
Craig reached the end zone three times in that game ...
FIRST FULLBACK TO LEAD THE NFL IN CATCHES ... Then things went nuts. 1985, the fullback led the NFL with 92 catches — two more than Washington star Art Monk, the future Hall
of Famer ...
"Craig remains the only player to make the Pro Bowl as both a fullback and a running back."
He was usually on the TE side...in the I he was the tailback, so there were some differences.
But McCutcheon and Perkins went to Pro Bowls as both a FB and HB but Pro Bowls never distinguished so it's all sticky. In 1975 Foreman led NFL in receptions
and was the FB that year (1976-77 I think he switched--McClanahan came in)
anyway, thought it is interesting of the levels of "accuracy"
