Chuck, was getting beat pretty convincingly. Tito we all know he needed a win even though he's been competitive. Wand, well I definitely feel he has fight in em still. But yes Dana has the right to state his opinion. Ultimately it's up to the fighter.
Chuck is an exception. He was 39 turning 40, has a daughter and he was getting his circuits shut down completely every fight; Rampage, Rashad, Shogun, and Rich with his off hand of all things.
It's good to see a well respected veteran speak up, but Dana is looking out for his fighters' interests. You see nobody has seen the effects of MMA fighter brains and cognitive abilities yet. It may or may not be as bad a boxers, but you can bet money that there's some brain irregularities in some of the fighters. My body aches after training in the gym with FULL PADDING...roflz. I can only imagine what these guys go through man day in and day out, week in and week out, year after year. Like I said they should have an HR department, sports psychologist, and in house doctors to scan their brains.
