This trade gives the Magic more players who create their own offense.
Rashard Lewis is an above average 3 point shooter, not someone you count on to be creative when the ball is in his hands on offense.
Marcin Gortat, while a very viable backup big, is traded. I'm guessing Orlando is satisfied with Brandon Bass backing up D12 at center.
Vince Carter creates his own offense, but the Magic have discovered what Vince's past teams have, to their chagrin, already discovered. That he is a selfish ballhog who takes away from the team concept rather than adding to it.
I, for one, am curious to see how this trade affects the Magic this year. On paper, this trade helps them... the pressure is taken off of Howard's shoulders to score. But by the same token, you only play with one basketball
