Whicker: Alvarez vs. Golovkin is boxer vs. slugger, but which is which?

When everything else is as equal as Canelo Alvarez vs. Gennady Golovkin seems to be, that is normally the bet. The fact that Canelo is a matador with sharp horns, and that Golovkin is a .300 hitter and his victims have tremendous exit velocity, is why Saturday should be one of boxing's indelible nights.
