So, I'm thinking Bruce Lee would want to fight in 145, after cutting.
That means, if he was good enough to get past the dizzying myriad of talented guys in that division, he'd eventually have to face Blackhouse fighter Jose Aldo, an extremely quick, extremely powerful Muay Thai machine, who's also a legit BJJ black belt, with very good wrestling. Aldo is a legit name to drop in any "best pound-for-pound fighter" debate.
Jose Aldo would destroy Bruce Lee, no question in my mind, and I love Bruce's stuff.
And all you Bruce Lee jock-riders would only make it worse for Bruce. Aldo would relish people doubting he could beat Bruce Lee. Look at what happened when people doubted him against Faber. He didn't just come out to beat Faber, he came out to crush every bit of him. He requested the fight in Faber's hometown, then he came out to "Run this Town" by Jay-Z as he soaked up the boos. Then he proceeded to dismantle Faber, and not just beat him, not just cripple him to the point where he had to be carried to the corner between rounds, but he absolutely tortured him for four rounds, before kinda having mercy on him in the fifth:

Jose Aldo doesn't just fight the best in the world...he destroys men. He takes the best opponents and cripples them, literally. World-class MMA athletes end up in crutches after fighting him. Urijah Faber wasn't the first, and he won't be the last.

You dudes talking about Bruce's dedication need to realize that there are hundreds of dudes swinging sledgehammers, flipping tires, and perfecting their holds, boxing, and muay thai, shooting takedowns and training cardio until they vomit in gyms all over the world -- in the middle of nowhere cornfields in Iowa, in dirty favelas of Brazil, in freezing gyms in Holland and Russia. Those guys are damn dedicated too, and the pool of dedicated fighters is soooo large and worldwide now.
And that's partly because of Bruce Lee. That's his legacy. That's what he'd be proud of if he were alive today.
