Yea, it's a very competitive fight between two undefeated heavyweights who have both looked great thus far in their careers. Both guys are taking a step up in this fight and both guys are taking on a big risk in taking this fight.
Abdusalamov has got some really nice KO wins on ESPN Friday Night Fights, and Perez has won Prizefighter and also has KO'd some top-50 opposition. On paper, this is very much an "even matchup" and I'd suspect betting lines will be close to even money (or perhaps, Abdu a very slight, almost incremental favourite).
It's refreshing to see undefeated heavyweights who aren't afraid to take risks and are taking steps towards fighting the best opponents.
Whoever wins this fight will move up considerably in the heavyweight rankings, personally I'd probably enter them into title contention and the top10. It's a very important fight and the winner will be moved up a long way.
Are there any white Cuban boxers?
The only white-looking Cuban boxer I can think of is
Richard Abril, the WBA World champion at lightweight. Ive seen him fight a few times and he is quite good! Very tricky, skilled, and awkward type boxer. If my memory is correct, he fought Brandon Rios a while back and beat Rios soundly but was robbed by the judges.
Most of the well-known Cuban boxers tend to be black. This is true in amateurs and professionals. I'm not sure why this is, probably because Cuban society tends to push blacks as athletes more than others, and erroneously believes blacks are more athletic. Of course, the irony is that
Whites tend to dominate amateur and professional boxing and this is increasing with each passing year. USA and Cuba used to be the dominant force in boxing, but they have both been steadily declining since the 1980's. USA has really went downhill. Cuba still produces some strong talent, but even they are showing signs of decline (or more accurately, just more Euro countries like Ukraine are producing better).
The best nation, right now, for producing boxing talent in the world would be Ukraine.
