I think it's important to do work on things like clutch so that GMs don't waste money pursuing the myth during free agency.
That said, as fans, debunking the myth can kinda suck. It's like playing the guitar. Sometimes learning how to play one of your favorite songs can kill it for you.
This is where the stats crowd misses the boat from a "PR" standpoint. Sometimes a little myth adds to the ambience-like Santa during the holiday season. It's hard enough discussing an argument when the premises are based upon metrics that many fans haven't considered or are complex making it difficult to sum in a sentence. Then ya go and kill Christmas with your conclusions too?
