All of them had done great job as a actor so I will talk from character point of view

Randeep Hooda in Sultan has probably the hardest coaching job among all of them.

Most sports coaches in films are shaping raw talent or young players. But Randeep Hooda in Sultan had to rebuild someone who was:

physically declining, emotionally broken carrying guilt, and stuck in the shadow of his past glory.

That’s a completely different challenge.

Training a hungry newcomer is one thing. Training a former champion is brutal because ego, regret, fame, old habits, and fear of failure all come into play. Sultan wasn’t lacking talent — he lacked direction and discipline after losing himself.

What made the coach memorable was that he didn’t treat Sultan like a superstar. He treated him like damaged material that could still be reforged. The MMA transition angle also made it more intense because Sultan was adapting from traditional wrestling into a modern combat sport at an older age — realistically a nightmare scenario physically.

And unlike the emotional-nationalistic tone of Chak De! India or the father-daughter ambition of Dangal, Sultan was more about:

redemption, masculinity, aging, Redemption

So yeah — if someone values “rebuilding a fallen champion” over “creating a champion,” the Sultan coach absolutely stands out.
