Personally, I don't see how you can compare Thompson's mount and Werdum's
Inconsistant reffing ........maybe, but I would expect the ref to use his judgement in every situation not letting it go b/c of a fight from last week
I still say it was a justified stoppage, Vera even said he wasn't getting out of it (with 20 seconds left), so ask yourself:
when has a ref ever allowed someone to take 40 seconds of damage when there's no chance of escape??
(btw, Thompson's 'Patty Cake' GnP doesn't count)
