There is a big, BIG difference between Cena's submission ability and Daniel Bryan's. I can't speak for LionDen, but what I detest about the STF is how it is applied and how Cena does it, it looks terribly unrealistic and terribly weak. He doesn't even apply any pressure and it's just ridiculous when that move ends matches. Bryan on the other hand knows how to properly apply the Labell Lock and do it very well.
