Lebron's, Jordan's & Kobe's careers at the age of 27...

[Smoke117]

please don't cite PER

doesn't account for defense (other than steals + blocks), has low consistency year-to-year, poor r^2 (both for individual and team outcomes), doesn't actually measure anything, comes from box score computation, etc.

use WS (and WS/48, DWS, OWS, and other subordinate metrics instead)

Yeah because accounting for defense is really going to help Kobe's case.

not every player enters the league at age of 18

So what you are saying is LeBron is the best of the three at 27? Well no shit man he is going to be the greatest of all time.
