I remember there was some talk that the Cubs weren't shifting that much last year, which was sorta weird, given Maddon was big on it and we have such a data driven front office (also Sveum was doing it a lot). Thought this was interesting...the data here (flawed in terms of sample, for sure) shows that, while the Pirates shifted over twice as much as the Cubs last year, the Cubs only saved one fewer run as a result of shifting last season. http://wrigleyville.locals.baseballprospectus.com/2016/02/04/some-notes-on-the-cubs-use-of-infield-shifts/ Again, not hard evidence, but the obvious implication would be that we may be better at picking our spots for shifts and that we MIGHT, therefore, be saving runs more often by not shifting in other spots, too, which is pretty cool to think about.
