You have a point, but the difference between Wlad and Dimi is that Wlad will actually hurt Chambers with the most jabs. And then after few rounds you will see that Chambers will start to fight as cautious as the two in order not to eat too many of those jabs. Although I anyhow have the feeling that Chambers will try to go all or nothing from round 1.
He won't. This will be another JAB, JAB, JAB, THINKS ABOUT THROWING THE RIGHT BUT WONT RISK GETTING COUNTERED, JAB, JAB, JAB, JAB, snooze fest like the Chagaev, Ibragimov, bouts were. Klitschko's jab, which seems to be both is offense and defense, is like a trip hammer, Chambers wont get passed it. Expect a bout to go 11-12 rounds, and put everyone to sleep!
