- [Narrator] Conor McGregor
is a mixed martial artist
with a relentless, aggressive style.
Known for his powerful spinning back-kick,
unusual front-leg hook,
and his lightning-quick
back leg roundhouse,
but now, he's taking on Floyd Mayweather.
(boom)
- And I'm the guy who has to teach
Conor McGregor how to box.
Being Conor McGregor's boxing coach
feels like a lost cause.
I've been training fighters
my entire adult life
and it takes years to make a pro.
Conor gave me three weeks.
At first, I thought this match was a joke,
like when Mitt Romney boxed
Evander Holy Field for charity.
When I found out that Conor
was facing Floyd Mayweather
for real, I had him sign a waiver saying
that I am not responsible when he dies.
Worst part is, Conor's only
with me two days a week.
He spends most of his time
off promoting the fight.
- I'm gonna knock him
out inside four rounds,
mark my words.
- So this is the boxing
gym where I train Conor.
This is a heavy bag.
Conor tried to jump up
in the air and kick it.
This here is a bench press.
Conor kicked it so
hard, he broke his foot.
I even put this poster on
the wall as a reminder.
It says, "Conor, stop kicking."
It didn't work.
Is Conor getting better at combinations?
No.
Is he getting better at jabs?
No.
Is he getting $75 million?
Yes.
I gave Conor a film to watch.
Ali, Frazier, Lewis.
I checked back a week later,
he had just been re-watching Bloodsport.
(grunts)
The only piece of boxing equipment
that I could get him to use was this,
Nintendo Wii boxing.
I guess it's something.
(boom)
Conor's not gonna win.
Realistically, he doesn't have a chance.
But, could he go out there like a champion
and make his family, MMA,
and the whole country
of Ireland proud?
No.
I've gotten used to his daily tantrums.
I keep a bunch of juice boxes
filled with Guinness nearby.
I usually have one or two myself,
helps me get through the day.
