Overeem won the 2010 K-1 GP. He's won the big one in K-1 but not in MMA.

weak tournament he fought two small HWs almost getting knocked out by both of them one who was injuried coming into the fight and then fought Aerts after he just did Overeem a favor by beating Semmy not that big of a GP win.

That's a fair criticism.
