WTF?!?! Wlad's left hook is devistating!!!! He hooks off the jab better than anyone I have ever seen.

The only reason he seemed to use just the 1-2 vs Chagaev is because Ruslan is a southpaw and that would open Wlad up to counters.

Witht he left hook and the left hook ALONE Wlad has: knocked down Ray Mercer and KO'd any number of opponents, the most impressive being Ray Austin as the shear SOUND of the punch tells you all you need to know about how effective it is, when I hear it, it reminds me of Hearns-Duran:
