Stats that have no impact on the outcome of the game.
An example of what I would define as empty stats is last season during a game the Celtics had against Charlotte, it was a blowout and Stevens emptied his bench, James Young came in and got hot and scored 13 in the 4th quarter. However the game was already decided and his scoring had pretty much no impact. That is what I would define as empty numbers.
I don't see how Cousins & Love were putting up empty stats. Yes their teams weren't good but they weren't getting blown out every night either. Cousins was putting up 27/12 while the Kings on average were outscored by 2-3 points every game, how does that have no impact on the outcome of games if they're close? It's not like he was playing for Philly or the Lakers who were outscored by double digits nightly.
