It's not as efficient
That is not necessarily true at all. Since we know this example (and every other fricking thread ever) contrasts Kobe and Lebron, then yes, 30/7 is likely more efficient.
Honestly, the games were so effective on both ends and there is a great amount of context to be considered that I do not know which stretch is more impressive.
I fail to comprehend why people disregard volume so much. Someone has to score the points.
In peak Kobe's case, it was Kobe Bryant or Luke Walton/Chris Mihm/Smush Parker. Yeah, I think I am okay with Kobe taking 40 shots a game.
In current Lebron's case, he is a great distributor and has also far superior teammates to the mid 2000's Lakers. I would be okay with Lebron taking only 15 shots, since I know that Wade and Bosh will also be contributing. My problem with the low number of shots is that it means that a number of shots could be coming from less reliable sources.
