Jim Harbaugh considers Muhammad Ali the most competitive athlete of all time - in anything.
Harbaugh got so giddy hearing his father's stories of recently spending a Ravens practice alongside Ali in Baltimore, San Francisco's coach shared it all with his players at the first possible chance.
That was last Tuesday. Five days later, the 49ers (2-0) dominated the Detroit Lions in Sunday night's 27-19 victory that showed this team is among the NFL's best on both sides of the ball and special teams with so many different ways it can win.
Harbaugh is finding different ways to motivate as well. Now that Ali visited his big brother, John, back East, Harbaugh figures it's time for the boxing icon to come see the 49ers.
And why not Willie Mays, too?
