Barnett has failed a drug test on 3 seperate occasions i have heard so he is just a plain cheater
arvloski well he is 0-4 in his last 4 and he has a bad chin but i do like the guy still
rogers- im sure he is a bum that crawled into the octagon, he is not top 10 caliber
werdum- is decent, great ground game but suspect striking which was exposed by fedor and jds to name a few
silva- he is okay but he nearly lost to lhw pyle recently and has not beaten anyone great hw
fedor- no description needed for this man, great fighter
overeem- very good striking, havent seen his heavyweight ground game much though and he has been koed a bit and has been koed at hw so that chin might be a bit fragile.
sergei kharitonov- the dark horse of the tournament whoo i think will make thew final and possibly win it, underrated, good ground game, brutal power, last man and only man to KO overeem at HW, has win vs werdum and has a good record.
thats my analysis of this, overeem is a great guy
