The biggest flaw in Ocean Eleven Movie

I hope all of you have watched the movie Ocean Eleven (first movie). Its one of my favriote movie. It has lot of mistakes. If you will search the you will get hundreds of it.

Here I will not talk about mistakes like visibility of camera crew or displacement of objects or repeatetion of action. Lets forget about all these mistakes. I have figured a much bigger mistake. Its in the Danny's plan.

Try to recall Danny's plan. I think there was no need for Saul Bloom's role in Danny's plan. Let me explain.

Do you remember that Yen(Japanese boy) who was put in the cash box and was sent to vault. Now the Saul Bloom's purpose was to sent the explosive briefcase into the vault. Now tell me when you can send whole Janapese boy into the vault, can't you you send that diamond shape explosive with him.

It may have lot of flaws but still I loved the movie. Actually I like all the ocean movies. What you say?
