I don't know if the problem is motivation or coaching, sparring partners, etc, but he did not look like the Fedor of old. Big Foot had a great game plan and he is a lot stronger compared to Fedor than I previously thought. Fedor simply gassed after the first round, he allowed big foot to get to full mount way too easily for a fighter of his caliber. Silva is something like 280 lbs and you can't really get a guy that big with a bjj black belt off very easily.
Anyways, He showed a lot of heart in defeat, he will always be a legend in my book, a class act both inside and outside the ring. good luck to him
