BBRef can be just as inaccurate, I'm just saying the lineups themselves are needed.
From what I can tell in the most recent game w/ Aldridge healthy against the Pelicans Lopez played 27:46 and Kaman played 20:14 (total of 48:00 at center). Beyond the Nets game where Lopez/Leonard started (only possible because the Nets effectively have a double-center lineup), I'm not really seeing any games where Lopez could have gotten extended run at PF as Aldridge has otherwise played a ton of minutes and the Blazers are still giving minutes to the likes of Robinson and Freeland.
It was used as an example regarding Lopez's situation, not on anything regarding this season.
