Aw man, RIP. First learned about Cliff when Bruce Springsteen covered Trapped in ‘85, then saw The Harder They Come as a midnight movie as a college freshman a few years later. That soundtrack and his catalog haven’t left my play pile. Banger after banger.

a badge of honor, as is the tag of being called a member of the vigilante sabermetric brigade by Bill Madden (as I was after doing MLB Network with him).

You'll know when we come rollin' through the streets.

I’m pretty sure I first used the line during a @baseballprospectus.com annual book tour with @stevengoldman.bsky.social and @christinakahrl.bsky.social, and it later made its way into The Cooperstown Casebook (2017).

So, we can all laugh about that when we take turns pissing on Cheney’s grave.
