Ok what the hell.
Overeem has improved dramatically, yes he is bigger (maybe roids) he hasn't been caught yet so he is innocent, either way he is one of the best MMA strikers if not the best.
Sure we haven't seen to much of him in MMA lately, but you don't need to be a scientist to work out that he will do extremely well against top tier opponents. He is probably the only heavyweight I would pick against Fedor right now, (maybe Cain)
Just because he hasn't been fighting in the sport doesn't mean you can't see how it will translate into MMA, especially with him fighting K1, which is probably the most benefical to MMA right now.
Overeem has become a kickboxing monster, we are lucky to have him fight in MMA, because it's a rare thing to have someone of his size and stand up skill in the sport. Whoever compared his k1 record to James Toney's boxing accomplishments needs to go have a sit in the corner and think about what you are saying, you are so far off the mark it's scary.
