Wlad is too complete a package for Haye to beat 95% of the time, however Haye is pretty quick, and he hits like mofo so if he lands that right cross cleanly I would believe Wlad would go down, however, landing that punch could easily not happen in 12 rounds, and Wladimir would definitely have the power to take Haye out with his left hook or right hand, hell maybe even his jab could put Haye on the canvas.
