I disagree. I had a SF with very low REB and that killed me in quite some games. The rebound matchup on the 3 does count a lot.
It's quite easy to train, that's another positive aspect. On the other hand, it counts heavily on the potential and salary.
That's the big advantage with passing. It hardly has any impact on both. The big problem is, that it's pretty difficult to train for a player other than a guard as you'd have to play out of position a lot.
