I don't think TS actually read that quote.
He's saying he's similar to Ali in terms that he's always the center of attention, he's always the guy in the room that everybody pays attention to, he's really clever with his talking, he's an amazing fighter and athlete, and the fact he's already a big star with only 4 (soon 5) fights is crazy. Nobody has really been able to market themselves THAT well. Chael may be the only other guy but his was all written & rehearsed, with Conor, it's the real deal. Like Ali, Conor is getting TONS of attention. He isn't in the media all the time for no reason.
He's not saying that he literally is as famous as Ali or some shit. No way will Conor have an impact like Ali did, nobody ever will. Ali is probably one of the most famous people that ever lived. You didn't even have to be a fan of boxing but you knew who Muhammad Ali was. That's not what he's saying about Conor.
What Lorenzo said is easily understandable, but unfortunately, people are going to take it the wrong way and act like Lorenzo is literally saying he is just like Ali when really, he didn't say that at all.
It amazes me at how people can't understand such simple things like this, lol.
