I agree SLE fits on the surface and I thought the same until my friend presented a great LIE argument. Now I can see him being either Si polr type.
The first thing I look at it with anyone is temperament, his screams EJ to me. Guy is always in control of himself. We can all agree he values Se, or at the least it's not his demo function. That video that K4m posted of him throwing the bike rack seems like he isn't actually at a loss of self-control. Not the way P's get. It seems like a really controlled hysteric for media attention and hype. All that chest puffing can be Se but he does it to a cringe point which makes it look like Se ha. Also his "swag walk" that he comes out on stage is like the definition of cringe Se lol. He's a great fighter, I don't think fighting and se have anything to do with each other. I know Ni bases who can fight and I know an SEE who is a complete pussy fighting, just bullies people.
Mcgregor's fighting seems more Ni to me. He has like an intuitive grasp on how to time his shots on opponents. This is pretty popular with VS cognition as well. SLI does this a lot. I find SLE to be more aggressive in a fight and use more brute force. Connor is very timed and precise. Stipe Miocic is an SLE fighter imo and he looks totally different in the ring and the way he fights and just how he carries himself. Donald Cerrone is another, the guy McGregor beat in like 30 seconds or something lol.
SLE fluctuate on energy. Connor just always seems wired EJ. He also talked A LOT of shit to Khabib just to get embarrassed in the ring. Then when Khabib was saying "talk now, talk shit now" or whatever during the fight, Connor replied "it's just business" I can't see an SLE ever replying like that after talking as much shit as he did. At that point you double down or shut the fuck up and roll over, don't start bs cringe se pleading after you tried to verbally annihilate this guy for weeks in front of an audience lol.

if this ain't Se ha then what is? lol
All that showmanship and "it's just business" etc etc looks like Te Ni to me behind the scenes. He's playing an Se base character on the surface for the audience.
