If you watched the fight last night then your question should have been answered.I don't get the "they don't fight big" argument. When you have a reach advantage, the goal is to keep the fight at a distance where you can connect but your opponent can't...and they do that better than anyone in history.
What does "fighting big" mean to you brehs? Hopefully not fighting inside and forcing the issue, the only place opponents have any chance against them.
There is defensive fighting that can be entertaining and then there is the bullshyt Wlad pulled with Povetkin.
That is why he (and to a much lesser extent Vitali) get no live from US boxing fans. They are not entertaining fighters at all.
Truthfully I think the sooner the two of them retire the more likely the chances of the heavyweight division becoming interesting get. There is a lot to be said for parity creating the illusion of greatness and with the Klitschko's removed from the board it takes away the two biggest and most boring obstacles to us having an interesting heavyweight title picture.
