At PF I value defense, rebounding, and versatile post scoring (aka, the definition of a PF) more than fadeaway jumpers. Pau scores from anywhere inside 18 feet, controls the paint, matches up with bigs, and is a better rebounder than Dirk. Dirk is more of a tall SF, and he is behind Durant and Lebron at that spot.
With an "ultimate" team there is going to be plenty of scoring ability at every spot on the floor, which means there is no need to sell out for scoring ability alone.
