No, it doesn't. Pretty much all the top ten players that most people can think of were extremely efficient, relative to their volume.
Kobe is an anomaly, honestly. He's pretty much JUST efficient enough to still be a positive because he takes such a high volume but efficiency is pretty big.
There's also the problem that Kobe will shoot you out of games even when other players are cooking and it can sometimes lead to a loss of rhythm for your teammates. There's good and bad that comes with a Kobe.
It's why Pau Gasol was one of the most genius pick ups for Kobe. He was an elite playmaking big man that didn't mind creating for others and gobbling boards. He's pretty much the perfect PF for a Iso Dominant SG(Kinda like Draymond Green is).
He was underrated because he was an all-star caliber big man who just happened to be competing against the likes of Tim Duncan, KG, Dirk, and Nash powered Amare, and CP3 powered David West( Plus China stuffing boxes for Yao) that made him fly under the radar.
But this is all fluff, Kobe's strengths do go beyond a box score but that holds true for all the greats. Lebron, Duncan, MJ, Russel, Shaq, etc.
