Are smart players too smart for their own good?

[HPG ADMIN]

Are the "thinking players" just a little too weak to make it to the #1 spot? Guys like Dan Harrington, Howard Lederer, Phil Gordon, and John Juanda get tons of respect - as they should - but always seem to never make it to a top place finish, while guys like Ariah and Hansen seem to have a better killer instinct. Are the smart guys just a little too timid compared to the aggressive ones?
