Sinan Samil Sam has very little lateral movement, and doesn't bob and weave much either. He's not as big as George Foreman, but he moves about as much as big George did during the latter stages of Foreman's career. I'm amazed that Sam has done as well as he has so far in his career. Tall boxers who can move give him trouble as you can imagine (Juan Carlos Gomez, Luan Krasniqi, Maskaev).

Dimitrenko:

is huge but his record suggests that he's more of a skilled boxer than he is a knockout artist.Vaughn Bean gave him a good fight and Chris Koval had him down in the 2nd round of their fight, so he's probably not as good as the Klitschko bros. He's only 23 years old though and might be a serious contender in a year or 2.
