Title describes it; it would be cool if the matchup data also reflected how the overall team performed, even if only a simple points per possession. That could answer some questions if a player really helped their team a lot even if the raw stats didn't look great.
I had actually put together something vaguely similar a few years back by manually inputting data from pbpstats which I'll link below if you find it a useful reference at all, but this tool is so much better. Great stuff guys!
