Steel Mamba
Nasty
P4P no, but top MW yes, why not?
It's not a SF vs UFC thing either as you're trying to make it out to be. Silva has beaten just about every MW that there is and most of which in convincing fashion. Fedor on the other hand, while still the top HW just wasn't as active as he should have been and since Pride he just hasn't faced all the top guys out there. Also consider where Werdum was ranked compared to where Belfort currently is. Werdum was recently bounced out the UFC on a bad loss.
Entirely different situations
