I have the distinction of growing up 50 miles southeast of Chicago and currently residing in N. New England, so I can clear this up for good.
MJ over Russel. All day, all night. GOAT vs an exceptionally good player fortunate enough to be playing in the NBA's infancy.
Orr over Hull. Hull was very good, but Orr was a once-in-a-generation talent. I think he was better than Gretzky in their respective primes. I don't think Hull is anywhere near Orr's level. Not even close.
I know jack shit about football or baseball, so I can't weigh in there.
