I haven't seen the fight Kirk only the finishing blow on youtube. I felt asleep at the PC, at about 3 after midnight the time here.
Can't give you a post fight comment. The only thing I can say is that I picked Broner simply based on the fact that Demarco was an underdog against a weaker opponent in Linares. I remember back then picking DeMarco watching videos of their past 2 fights. Noticed that DeMarco was a good pressure fighter with decent pop and combos, and Linares couldn't really managed to keep some guy off him in some rounds.
