As mentioned before, Nene is one of the most efficient and effective Low Post scorers in the League. Yes, he sucks at rebounding for his size....but over the last 3 seasons....he averaged 14.3 ppg on 8.8 FGA while shooting 60% while taking 5.1 FTA line while making 70%. He's very effective on the scoring end by putting up 14+ ppg while not requiring the need to touch the ball on a regular basis on the offensive end.
Putting up these scoring #s is not an easy skill to learn and IMHO a very valuable skill.
If you want to have additional scoring threats in the Frontcourt that doesn't require the need to have ball in his hands ALL the time ( which also means that you can allow more touches for the rest of the Team ) in order to put up decent scoring #s....then Nene is your guy.
