The Cubs are 9th highest in Z-Swing, 17th highest in O-Swing, while being 12th in Swing % overall. I don't see an easy way to break that down by count, but considering they're 19th in Ks and 9th in BBs I don't see any reason to think they're a big outlier. I think the degree to which that gets noticed is due to 1) taken strike threes are way more memorable and 2) there's a league wide shift due to how much harder pitch recognition is with tunneling and how good pitchers are at inducing chase.
