when i say he defends until they gas, i don't mean that he literally clams up and does nothing. but he does conserve a lot of energy only defending, while the other guy is trying his best to submit him. since there are no points, he can sit back and not worry about getting passed a gazillion times. he did it against keenan, he did it against pena. of course he goes for stuff, but the top guys handle it just fine when they aren't dead tired. see, you will again try to spin this as a knock on the kid, when it really isn't. the rules state he can do this, and he excels under those rules. what i'm saying is he (and fucking danaher) acts like winning under those rules is the only true measure of skill, when it really isn't.
If you count the # of submission attempts that Gordon has vs his opponents I would be very surprised if any are ahead of him.
Some may pass his guard or show some positional control, it's normally not for long at all and a lot of time it's off a failed sub attempt.
Positional control, specifically the kind I've seen Gordon put under where he recovers very quickly, can definitely be argued as far as its effectiveness outside points tournament. If people were dominating position like little Cobrinha did to Nicky Ryan that'd be different, I haven't seen anything close to that from Gordon. I like the IBJJF ruleset but I've heard Danaher say that submission is something we can all agree on. I have my preferance but I can certainly see Danaher's logic and Gordon's matches that I've seen are a great example.
i mentioned tournaments, because it's how anyone can make a name for themselves in BJJ. you want buchecha, rodolfo, marcelo's top 3 so bad? enter any of the tournaments they compete in and kick their ass. that's what people normally do. hell, that's how these very top guys built their names, by entering tournaments and mopping the floor with the previous champions. they didn't put on a plastic crown and challenge them in an instagram post, then bitched about being avoided when matches aren't agreed upon..
Gordon isn't eligable for IBJJF tournaments since he got promoted too quickly. He competed in several other organizations in 2016. Alot of the guys you mention compete in IBJJF almost exclusively, which he can't.
