You could be right. While Lebron, Wade and Bosh would be one of the greatest trios in NBA history, chemistry might be a problem.
They are all fairly unselfish players, but James and Wade are both used to having the ball a lot and having being the center of the offense. Also, neither of them is a consistent outside shooter, though I imagine they will be able to find a player or two to fill that role.
Don’t get me wrong, they could dominate the NBA, but signing all 3 will not guarantee a title.
Wade is not a selfish player.
He was selfless at Marquette to the point where he slipped in the draft. No one believed he was a star, but rather an above average complimentary guard.
