If someone is still in it, the fight shouldnt be stopped. The only time I think it should be stopped is when somebody goes limp, or a cut is too damaging. Maldonado went through hell, but still had a punchers chance and we've seen it many times before. He shouldnt have been stopped after leaving it all out there and wanting to continue. He was on his feet and he could throw punches. That's enough. Silva was under a full mount, which is the only reason he took shots. He was trying to get out of it, blocking, and doing everything he could from the position. Neither fight should have been stopped imo.
I'm probably the best at keeping threads on topic of all time.
