When Chuck Foreman shows up as a substitute teacher in Bloomington, his students already know plenty about him.
Some have read about him on the Internet and watched highlights of the running back starring for the Vikings during the 1970s. They often state their approval when class begins.
"They say things like, 'Mr. Foreman, you're the real deal,''' said Foreman, who primarily serves as a substitute for middle and high schools.
They also sometimes ask why Foreman isn't in the Pro Football Hall of Fame. To him, that's long been a mystifying question.
"There's no question I should be in the Hall of Fame, " said Foreman, 64, who lives in Eden Prairie and also runs a commercial cleaning service.
