Considering the numbers for most guys over 6'10 in the nba:
A positive point differential of 0.3 per game whilst on the court is pretty meh.
Players like Jokic, Gobert, Meyers Leonard, Cody Zeller, Mahinmi, Favors all do better in that differential. Its not like they're studs or on dominant teams.
Last year at a positive differential of 1.1 whilst on the court is a little bit better but still meh.
I get your argument that hes a little flower growing in a pile of crap, but using his pithy positive point differential to justify him being a massive get in a trade doesnt really fly.
This years differential could be back where melo's is with a couple of bad games.
You're cherry-picking here. I looked at all the teams near and below the Kings in the standings, and showed how rare it is for a low lottery team's best player to have a positive point differential. What you did is something different all together.
Favors (who is, in fact, a stud), Gobert, Zeller, Mahimi, and Leonard are all on teams either slated for the playoffs, or within one game of a playoff berth. They all play for teams that rank in the top-14 of team point differential. Its not shocking that guys who play on good teams would outscore their opponents.
Jokic is the only example of a guy with a positive point differential on a bad team, and he's only averaging about 21 points per game. Again, that's not an apples to apples comparison.
And, it's not like being 6'10" somehow guarantees a positive point differential. Did you overlook the guys I cited? Anthony Davis, Brook Lopez, Jahil Okafor, etc.? All are 6'10", all are their team's best player, all play on bad teams, and all are being wildly outscored when they're on the court.
The Kings are a bad team. Yet, the Kings outplay opponents when he's in there (and get killed when he's off the court). That speaks to his impact.
As I've mentioned previously, ESPN's "RPM" stat tries to take stuff like this into account, with their "Real Plus Minus" stat. Cousins has been top-12 the last two years.
