People that are saying Anderson is scared clearly doesn't get the big picture. The man is 37, has been fighting for a living for well over 15 years. He has seen and fought the best, why would he be scared of a up and comer?
Really man some of you people and your delusional thoughts. People tend to forget these guys are human also. The dude has four kids who are all under 18 i think. Do you really think he is taking time off because he is scared of a fight? I'm pretty sure he wants to spend time with that family that he has likely has neglected for 15 years, trying to be where is at today.
Chris Wielman is chasing a dream, Silva has done it all, money is no longer an issue. Look at the list of fighters who have retired just to spend time with their family:
-BJ now he is back, but go watch the interview after the Diaz fight
Simple fact is Dana White calls the shot, when Silva returns Dana picks his next fight. Bottom line is there is nothing for the man to do in the sport he has done it all but lose. If you were Anderson Silva and at your peak, wouldn't spending time with the family be more important at this point?
