Chuck Lidell and Tim Sylvia DO fight in a similar way, but that's like saying Rich Franklin and Nate Quarry have a similar fighting style. Accurate, but a little misleading. Lidell implements his fighting style better.
Lidell's real strength isn't how hard he hits. There's a ton of guys in the UFC that hit like a truck, but none of them are the Iceman. It's not that Lidell can hit hard - it's that he knows WHEN to throw that crushing blow. Remember the second fight against Sobral? Sobral charges forward, looking for the takedown, and Lidell just backs off, chambers that monster right, and waits until Sobral overextends himself, and BOOM! Fight's over. That stuff happens, but when Lidell is doing it to Sobral, Ortiz, Couture, Horn, it stops being luck, and starts being talent.
How do you fight a guy that has a knockout blow waiting for you the moment you miss a step, or drop a hand an inch too low from your face?
I think everyone can agree - the guy who defeats Chuck Liddell is going to be one hell of a fighter.
