Wlad had to stalk Haye down for 12 rounds and people routinely confuse "being smart" with "being cautious"...Would Wlad have been smart if he just walked right into one of Haye's haymakers? NO! So Wlad stuck to his game plan (which has never not worked) pump the jab, look for openings, and don't get caught in return.

And who says Vitali "wouldn't be able to find Tyson"?!?! If anything Tyson would have a hard time finding Vitali, Sanders caught him as did Lennox but those guys are significantly taller than Tyson.

Bobbing and weaving doesn't mean much if you can't get passed the jab. The guys that use head movement to work to the inside of the Klitschko's are routinely tied up, out maneuvered, or walked into punches.
