I can easily see another Wlad vs Sultan easily. Before that Iggy was one of the better heavies, typically having exciting fights and using combinations and footwork (he did in the few fights ive seen him in). However the height and jab just got to him. Hopefully Chagaev can do more but I see the same thing. Don't depend on Wlad to impress- in his last fight Rahman was begging to be ko'd from round 2 but Wlad just kept him there- and that was one of his more recent exciting performances. Ruslan has to get inside and work- Wlad can't fight inside. He can't allow Klitshcko to get a ryhtm with his jab or he'll get mesmorised (always used to happen to RJJ opponents as well). I'm gonna go against my instincts and say Chagaev close UD by taking advantage of Wlads slow start- the 2 week change of opponent can be the deciding factor.
