A Reddit user found a somewhat accurate way to predict what kind of game James Harden's going to have (and it has nothing to do with which refs call travelling). User AngryCentrist found that Harden had a significant decline in performance in cities with a reputation for having top-tier strip clubs.

By cross-referencing 4 seasons worth of data with the average review of the strip clubs that appeared when they typed in "[City] Strip Clubs," AngryCentrist found that Harden had more off-nights in cities where he was likely to have a late night the day before.
