Bosh is the ideal international 'big'.
He is a perimeter oriented 4. Because of the short 3 point line and trapezoid lane, it really makes for a smaller game.
It's usually why international bigs are more perimeter oriented, or at the very least have a good midrange, just no need to develop low post moves in the international game considering the 'low post' is 10 feet from the rim, not exactly the same thing.
With that said - because Bosh runs the floor well, can shoot, and play outside the lane it makes him the perfect guy for the int'l game.
Bosh isn't a great defensive player, Dwight is better based on blocks and reboudning, Bosh just looks better because of the style of play.
