Mikes still got some of the fastest hands in the heavyweight division. Teach him to defend Ricksons weak takedowns, and he'd probably win. Even Funaki caught Rickson w/ some shots, and if those were "Mike shots", he would have been done. Plus Mike would actually be the way younger of the two. Mike may not be a top 5 heavyweight anymore, but Rickson never even fought anyone "top 10" in anything other than sport bjj.
