You don't have to trick your opponent if you execute well. If we have a play that averages 5 YPA, I say keep doing it until they can stop you.
Yeah, I like the end around. If it's set up right it gets the ball in a fast WRs hands with room to run, they used it with Cotchery too. You just don't want to get caught in the backfield, especially if you're in FG range.
