GSP tapped to an armbar before he tapped to strikes, so he's even better at that -- you should give him credit for being the best at that too. Or did you just not know he tapped to Hughes in the first fight?
Beats me why he gets so much more trash talk for tapping to strikes than the armbar, given that any doctor will tell you that strikes are way more dangerous than armbars (that is why several national medical associations want to ban boxing and MMA, but none want to ban judo or BJJ -- arm bars simply aren't considered medically dangerous, head strikes are).
