Khan easily dominated Kotelnik, Judah and Malignaggi. The same Kotelnik that later beat 147lb champ Alexander according to most except the judges. Khan fought and beat Maidana, after he had destroyed Ortiz and was considered one of the hardest punchers in the sport. Judah had beat Matthysse and was the champ when Khan fought him. Since Khan destroyed Judah he has beaten unbeaten Vernon Phillips and is now fighting for title against Garcia. After Khan destroyed Malignaggi he has gone on to become a world champ at 147. He was beaten in D.C by a juiced up Peterson and biased ref even so it was a razor thin win for Peterson. Sure he was demolished by Garcia by the one punch that turned the fight. I do have an issue with Khan being ranked at #2. However, your assessment of his accomplishment and attempt to trivialize it is transparently biased.
I'm not going to argue as to how much of a good example Khan is. All I'm saying is he fights the best and in that way he credits the sport. What people say after a defeat is up to them. If your offended by it, that's not his problem. If he wants to hire a new trainer, go ahead! Some of the tosh on his twitter account and the comments he's made I don't really care for, but I'm more interested in what he does in the ring. Also, that bit about delusions and entitlement was nicely worded, but shows you clearly have never seen the man speak. Fair point, I wasn't fully aware of that situation.
