It is about time Kharitonov received some recognition for his accomplishments. Kharitonov has now defeated a solid list of fighters including Andrei Arlovski, Alistair Overeem and Fabricio Werdum. If it weren't for a loss to Jeff Monson in 2009, Kharitonov might have made this top ten list.
Overeem's current nine fight winning streak began with a win over Paul Buentello. It continued with wins over Mark Hunt and Gary Goodridge, fighters who are riding losing streaks of six and eight respectively. Overeem's most recent wins came against opponents, Brett Rogers and Todd Duffee, who are still unproven against top competition. Overeem has potential to climb these rankings quickly, but he will have to beat top-flight competition before he does. That climb could begin by avenging a loss against Fabricio Werdum.
Barnett has an argument for a position in the top ten as well. However, Barnett has not exactly fought any elite heavyweights on his current winning streak. The last times he did, Barnett lost to Antonio Rodrigo Nogueira and Mirko "Cro Cop" Filipovic.
After his last win over Gabriel Gonzaga, Schaub is a somewhat surprising addition to this conversation. After being knocked out by Roy Nelson at The Ultimate Finale 10, few would have thought that Schaub would come this far. Still, given Gonzaga's decline since his win over Filipovic, Schaub still has some work to do before he breaks his way into the top ten.
Mirko "Cro Cop" Filipovic
Filipovic's most recent losses have come against excellent fighters in Frank Mir and Junior Dos Santos. It is Filipovic's lack of wins against noteworthy opponents that has him on the outside of the top ten looking in, though. Filipovic's last win over a top heavyweight came against Barnett more than four years ago.
