Patrick Cote suffered an unfortunate injury in the third round of his fight with Anderson Silva at UFC 90, and the fight was stopped early. Mike Goldberg immedately said Cote had earned himself a rematch.
Realistically, he did nothing to earn a rematch. Silva looked actively bored, and simply toyed with Cote. My guess is he was trying to have a longer fight, carry Cote into later rounds, and then finish him there. I have no idea why, maybe he is just bored, but Cote was so clearly out of his league that it was frustrating to watch.
To conclude, Cote does not deserve a rematch because Silva decided to mess around. The UFC got what it deserved in this fight for booking such an uncompetitive main event. Anderson Silva is also mistaken if he thinks fighting this way will make him a star.
