Combat Sambo

If anyone watched the fights last night, ufc 160 you saw a master of combat sambo in Khabib N throw his opponent all over the cage.
Sambo is well known for its explosiveness, quick submissions and huge pick ups and throws. In combat sambo comps you also have to deal with headbutts!!
Its no wonder these athletes transition to mma so well.
Here's a vid of a beautifully executed head butt k.o. and a highlight from the Russian championship, also a headbutt k.o. at around 2min 12.
