exactly what everyone was saying about mir.
here's how i see it:
gsp - out of the question, no competition at wleterweight for him.
silva - a couple high caliber middleweights, but they way he's picking bigger LHW apart, i don't see him losing
Lesnar - still being underestimated in my opinion. The most physically dominant specimen in the ufc, I believe he will take all fights where he wants them to be fought
Machida - Some good competition for him, but he's so well rounded, and seems to have perfected his gameplan of eluding strikes, and picking apart opponents.
Penn - Seems to dominate the competition he has bee given at LW, but i believe (probably heavily biased) that sanchez can take him. (note I hate bj penn and sanchez is one of my favorite fighters)
