If you doubt me I can provide you 5 examples of fighters who were "out" and they were no where near immediately popping up the way Robbie was.
I can go back to all the UFC's history of fights, and find ONE example of a bulldog choke, and that dates back to UFC 31.
This choke was successful b/c it was under the chin, ie a choke not a crank.
Watch for yourself. Then re-watch Robbie's end fight. Beyond that, I have gone out of my way to talk to people I have rolled with who will mop the floor with me. Black Belts, Brown Belts, Purple belts, former UFC fighters, current UFC fighters, and they all are the same stance, it was not a choke he was not out. Of everyone I talked with, only the purple belt went out of his way to agree with me that the arm going limp seemed awkward.
You need to provide examples of this choke being done, and the reason you'll have such a hard time finding these examples, is because the choke is extremely hard to pull off on a high level. THERE'S A REASON YOU DON'T SEE THIS BEING DONE IN THE HISTORY OF UFC.
Do you guys think Ben Askren is bringing a new move to the table? He's not.
In Ben Askren's mma career, he never had a bulldog choke prior to this fight.
In Robbie's mma career, he's had no issues tapping to chokes from Evan Tanner, Jacare, Jake Shields, Mayhem Miller. But all of a sudden Robbie's just going to go to sleep instead of tapping?
No.
If the claim is he was out and woke back up, what was he out from? If you say an oxygen choke, then tell me how one can get an oxygen choke when the arm isn't underneath the chin? If you say it's a blood choke, then find me ONE example of someone being put to sleep via a blood choke, and they immediately bounce right back up.
ONE example, that's all I ask.
