The best players are the ones that can drive to the hoop, draw fouls, and make free throws. LeBron. Kobe. Pierce. Wade. Roy.
Those are the elite swingmen in the game. Usually they are in the best position to finish at the rim due to their size and athleticism (not to mention their ability to shoot as well). Unless you can shoot as well as someone like Reggie Miller or Ray Allen, you need to be able to drive, which creates for yourself, makes the defense adjust, and thus creating opportunities for others to get open as well.
If you have a DOMINATING big man, you can dump in inside and play inside outside, like how the Rockets won back in the 90's with the gunners like Maxwell on the outside.
We're in a pretty good position. We have good shooters, multiple people who have shown or proven the ability to create and finish at the rim (Roy, Outlaw, Bayless), a bruising big man in training (Oden), and a finesse PF who can shoot the jumper, score on hte block and play solid defense. Add a few solid pieces like good shooters (Rudy, Webster) and a backup bigman as solid as they come (Pryzbilla). Pretty good core if you ask me.
