UFC has come a long way from the 350 lb guy fighting the 160 lb karate guy for 15 straight minutes.
it's better that there is other ways to beat guys other than KO.
look at Brock and look at the Silvia-Noguera fight. Silvia rung his bell and had him pretty much beat in the first 3 minutes or so ..nogeura weathered... 2 more rounds then pulled a guillotine choke for the win.i thought that fight was real bad because Silvia is hated by just about everyone. the heavyweights suck most times because they lumber...and get winded quick..then make a long fight not doing much .....OR have a 45 second match with a quick KO.this show was forgetable it was probably the worst PPV i've seen in the past 2 1/2 or so years.
light heavy and below put on better fight even if they are quick KO's or Submits.
So you'd really rather watch, say, UFC 61 with a 5 round snoozefest between Sylvia and Monson, or UFC 78 with no meaningful matches?
That's part of what makes MMA so great, the way a fighter can come back from almost certain defeat to a stunning victory. The fact that Nogueira has made a career of doing that makes him even more admirable IMO.
