Maybe a need to reassert oneself in a sport that's seemed to change so much over the years? Making a triumphant comeback to capture the fleeting glory of days past? I feel in MMA, there's a habit of throwing phrases such as, "Yeah, Rutten was a legend, but he'd be destroyed against today's fighters...ditto Royce, Ken, etc..." This kind of thing only works in pro wrestling nowadays, and even then it's definitely hit and miss. The learning curve and recent experience gap just seems to be too daunting for a single-styled old schooler like Rutten to really make a heavy impact again, or any real impact at all, for that matter. Legends definie a sport and blaze the way for future generations, but they're not all that great at returning to it years down the road to compete with a fresh new crop. Ultimately it just diminishes an amazing legacy with a series of recent losses and slight wins.
You threw it out perfectly, Pumba; what do any of these men still have to prove?
Although if Royce's rumored payoff is accurate(1.3mil+percentage of ticket sales), a really sad prospect is that it's worth it to these men to diminish their legacy for a six to seven figure payoff with a beating attatched to it. Even though Shamrock's return has been less than stellar, he definitely hasn't been in it for the money; gives we few still left on Team Shamrock some definite comfort. |
