Concerning mixed feelings about two white boxers fighting each other, this is only a natural development of the slavic takeover of the heavyweight division. We can't have it both ways. If many white fighters begin to rise up in the ranks, like Chagaev, Povetkin etc. obviously there will start to be more and more white vs. white title fights.
For instance, Povetkin will be fighting either Brock or Chambers in the IBF eliminator tournament probably early next year. Should we be hoping that Povetkin loses to a black fighter to avoid a Klitschko Povetkin title fight sometime in the summer of 08?
Or should we be upset that Valuev and Liakachev will fight in the eliminator in the WBA ( or whatever Chagaevs belt is in) for the right to fight Chagaev? Should we be upset that its not Valuev vs. Ruiz, or maybe Holyfield vs. Ruiz, or Mccline vs. McCall. A byproduct of the Slavic dominance in heavyweight boxing should be more and more whites only eliminator and title fights. If thats not the case, it would be a bad sign. Let the black fighters go down in the fights leading up to the eliminator fights is what I say.
Depending on which ranking you look at, white fighters are a clear majority in the top ten, and this too will have an impact on who is getting in to the title fights.
