BDD: Chris Jaffe on Managers Part II

The latter portion of my interview with Chris Jaffe is up at Baseball Daily Digest. Here’s Part I in case you missed it.

I know he’s a pitching coach, but I’d love to get your take on St. Louis Cardinals’ pitching coach Dave Duncan. I hear — and see — that he works wonders. Do you buy it?

He’s done a great job.  Where does Dave Duncan end and Tony LaRussa begin?  I definitely give Duncan more credit for what’s happened to pitchers than his boss, but pitching coaches aren’t magic bullets and can’t be easily divorced from their surroundings (a statement that holds true for managers as well).  If you don’t believe me, ask your friendly neighborhood Orioles fan what he thinks of Leo Mazzone.
