Dempsey vs Tunney is the equivalent of Pacquaio vs Marquez. Aggressive, explosive super fighter, vs patient, rotating, combination throwing counterpuncher. It will prove to be the same circumstances in another way too. Wills would likely have utilized his tall boxing style and beaten Tunney, but Dempsey would have knocked Wills out. Just like Mayweather was able to control Marquez, but Pacquaio will dispense a multi-dimensional ass whippin on Mayweather.
