College basketball stat websites should track player consistency. Start with tracking how well a player does during their non-conference, conference, and top-25 (50, 100, or just strength of opponent) match-ups and then combine them in some ratio and track it. This seems like a metric for predicting future player performance within reason. I suspect there's a trend there where a player has a good or bad game ratio based on the number of games they've played.
Random related thoughts:
Perhaps some players are consistently more reliable when it comes to playing bigger ranked teams?
Does time of day impact player's performance?
What's the likelihood that one player pulls the rest of the team down when they are having a bad game?
These all seem like possible factors in future performances or at least interesting points to study.
