也许有人会举出PER的例子来说明保罗比科比更优秀。
我认为这是不可靠的,首先Hollinger自己就曾说过PER的缺陷:
Problems With PER
PER largely measures offensive performance. Hollinger freely admits that two of the defensive statistics it incorporates -- blocks and steals -- can produce a distorted picture of a player's value and that PER is not a reliable measure of a player's defensive acumen. For example, Bruce Bowen, widely regarded as one of the best defenders in the NBA (at least through the 2006-07 season), has routinely posted single-digit PERs.
"Bear in mind that this rating is not the final, once-and-for-all answer for a player's accomplishments during the season. This is especially true for players such as Bruce Bowen and Trenton Hassell who are defensive specialists but don't get many blocks or steals."
Neither PER nor per-game statistics take into account such intangible elements as competitive drive, leadership, durability, conditioning, or hustle, largely because there is no real way to measure these things, which are often based on opinion and hearsay.
In addition, some have argued that PER gives undue weight to a player's contribution in limited minutes, or against a team's second unit, and it undervalues players who have enough diversity in their game to play starter's minutes.
