Look at the match where I the Mexicools were facing I think MNM. Nitro has Super Crazy in a pin and when the ref is about to make a 3 count but stops and then Juventude jumps from the turnbuckle and breaks up the pin. Wow Juevy needs to be faster.
You'll see that in a lot of tag matches. It's actually not the Referee's fault but the slow (most likely fatigued) wrestlers. Atleast he didn't tap for 3. I've recently seen a match where a Referee accidentally tapped a 3 (Carlito vs Masters at NYR PPV) It had to end early. Now that is a slipup.
