I know I am in the minority, but I do think the whole "MMA has evolved so much from 10 years ago" argument is slightly overplayed. Yes, as time goes on, sports improve because of training and strategy etc. There are plenty of fighters who are successful now who really don't look any different from 10+ years ago. I think Woodley today is worse than GSP was. I don't think Whittaker/Rockhold/Weidman are any better than Anderson. I don't think Stipe or Cormier are lights years ahead of Brock or Rampage/Chuck.
Sure, I would say on average the fighters are better today, but in a sport like MMA that could end up not meaning anything. Being more well rounded does not always = victory. If we are talking the early and mid 90's, then sure, the game was completely different. But the mid 00's until now I don't see a massive change. I just see guys training more disciplines opposed to mastering 1 or 2.
