Frank Gore says he is a surefire Hall of Famer ... telling TMZ Sports if you think otherwise, you straight up don't know football.
"You go ahead and ask any coach, any old player, any -- tell them to call Bill Parcells," Gore says. "Anybody. Call anybody, and they'll tell you what type of ballplayer I was."
Gore's numbers say he's a first-ballot Hall of Famer -- he is, after all, third on the all-time rushing yards list with 16,000 -- but, still, some pundits say he doesn't belong in Canton.
