I think the hugs after a match are an ultimate sign of respect. To me no athlete trains as hard as a great wrestler does, so win or lose that is showing respect to your competitors because you know how hard they trained to get there. You see it all the time in MMA with grown men. They beat each others faces in for 3 to 5 rounds and talk a lot of smack before hand, but when the final bell sounds everything changes you see that sign of respect and hug, because you know how hard it was for each to get there no matter who wins.
