... In fact, if you were to go back for as far as ESPN keeps PPS data (1999-2000), Harden has the best single-season Points Per Shot of any NBA guard during the 13-year span, and Chandler’s 1.97 PPS is the best overall PPS in at least the last 13 years. To put Harden’s feat of 1.66 PPS as a guard into even more perspective, neither Michael Jordan nor Steve Nash nor Ray Allen ever broke the 1.5 PPS mark. And while dead-eye assassin Reggie Miller has broken 1.5 several times, he’s never cracked the 1.6 PPS mark.
