I think its because of all this "be aggressive" narative. what does that even mean? instead of concentrating on team properties such as "we need to execute better on pick and roll" or "we need to run this or that play with better movement/picks/awareness", there is a lot of emphasis on individual properties as in "this or that player needs to be more aggressive".
yeah? more aggressive? as in drive into traffic and fumble the ball? put up shots after one pass? just be aggresive man and the ball will go into the hoop. what you lack is aggression. lets take turns being aggressive. this advice maybe works for Harden, but that's it.
EDIT: ok, that was a rant which oversimplifies the issue, not sure where it actually came from
