'Sacrifice': Why Coach Khabib's run will end soon

Khabib Nurmagomedov's father, Abdulmanap , was the team's founder and lifeblood.

The legendary coach assembled the core of this group when they were children in Sildi , a small mountain village in Dagestan .

He is the only one who can carry his father's plan to completion -- and that alone is what makes it so difficult.

Nurmagomedov 's cousin, Umar , will challenge bantamweight champion Merab Dvalishvili in the co-main event.

Khabib Nurmagomedov's stable of fighters have a combined record of 91-1 .

The UFC lightweight champion stopped cornering his fighters and publicly said he had no intention of ever doing so again.

He took over Abdulmanap 's role as coach and guided teammate Makhachev to the UFC 's 155-pound championship.

The team's goal is perfection, and perfection requires sacrifice.

Nurmagomedov 's coaching style is nearly identical to his father's, according to the team.

He has made it clear that the lives and careers of his fighters are up to them, but he still has that stoic honesty he had as a fighter.
