The guy who’s rolling with Eddie is double of his size and strength. Regardless his belt, you can see he is not a fool on the floor. If you know anything about fighting you will realize that it’s not how fast you submit your opponent, it’s about how you set up your game to get the submission.
You won’t see Eddie in any bad position neither being threatened by the strong man who seem to have a good ground game as well.
Nowadays we need to have an open mind and accept the fact that strength, heart and conditioning are real factors to a fight or a roll that can be counted as same as techniques!
