carvalho one was not good. but it happened at a time where there was a big movement in "protecting the fighter" going on. Also, wiman choke on danzig is inexcusable.
the kyle bradley stoppage was justifiable as he fell flat. i personally think if they get up the ref can always change his call if he thinks the fighter can continue. and that brings me to brown/sell. i applaud him for realizing he wouldve had called it early and so he let them continue fighting. i think most of his instances were dishoveled and looked sloppy... obviously it could have been executed better.
overall, i think hes a good ref who has had a bit too many mind farts.
hes not as consistent, as say, herb dean.. but herb might stop a fight if a guy trips over his own foot.
oh and dan miragliotta is finally becoming a somewhat decent ref. he usually kinda bad
