Is it just me who suspects that Blaze Lee would not necessarily benefit much from being talked into taking a Judo class?
Judging from what I've seen and heard so far of Mr Dragon, he seems like the preacher type, constantly telling everyone who's willing to listen how the world works. His ego is huge, and he probably avoids any type of situation where it might get checked.
If he did agree to taking a Judo class, I think he would show up with numerous "injuries", and then sit out on any excersise he deemed to strenous (which would probably include the warm-up). And if he did agree to sparring (not very likely), he would probably start lecturing in the middle of a roll, talking away while being mounted or in the middle of getting armbarred, telling whoever's schooling him about the deeper, spiritual principles behind the martial arts - shaolin temple this, sport versus street that, uprooting priciple this, and why what he's doing now wouldn't work if they were fighting f0r r34l.
After having talked and rested his way through the class, not even breaking a sweat, he would walk his fat ass back to his parents basement, smugly contemplating his superiority in martial wisdom compared to those base, worldly judo-players.
So, I'm hoping I'm wrong, but that's basically how I would envision it going down.
