The stall call was legit, and pretty much textbook, now stalling is a judgement call, and many officials may look at it different but I completely agree with both stalling calls, both calls were almost identical, imo he never lets go of he tight waist and shows me no attempt to execute any type of break down move and or any type of move to attempt to turn and or pin his opponent, he never tries to leave his safe place of riding behind the hips.
As for the possible takedown, I can see it being called and see it not being called, now even though its a great look by the camera, its completely different feeling and look on the mat. Imo its very loose, and I still have continual motion by both wrestlers, if there is control I don't know that I have it past reaction time, as if wrestler a is covering his 3 points of control its held exremley loose for me in this scramble, enough for me to warrant letting it burn till they settle, now im not the official on the at and what his thoughts were, but I did see him confer with his assistant and its seemed as if they both agree, it is a very tough tight call
