In market research, one of the things you learn quickly is to be very careful about presenting statistics to marketers and executives because it is not uncommon for them to latch on to one number (that typically aligns with what they want to believe) and overlook the big picture. I get that OPS, K/BB rates are not the end-all, be-all predictors of future performance. I get that park (Brevard County - notoriously tough on RHH, Colorado Springs - hitter friendly) and league (Cal league - very hitter friendly) factors need to be taken into consideration (and I take them into consideration). However, those stats tend to be the "big picture" stats for hitters. I've heard about Nottingham improving, but when I look at the "big picture" stats I see a sub-.700 OPS and a BB rate <10%. His K rate has improved significantly (30% last year down to 19% this year), and he has a nice differential between BA and OBP, but that differential is driven by an abnormally high number of HBP (already more this year than all of last year). I get that he's two years younger than league average, and that's encouraging. But to me, the big picture says, "encouraging, but still not good", because, generally speaking, a sub-.700 OPS and walk rate of <10% at AA don't translate to future major league success. There's an old quote - "Potential is a French word - it means you're not worth a damn yet." There was another thread where I got into a debate with someone about Corey Ray, and that person brought up some stat that showed he hits the ball harder than average for the league or something to that extent. That's great, but one of the issues with him is his K rate - he's striking out 32% of the time. It's nice that he hits the ball harder than most in his league, but 32% of the time he doesn't hit the ball at all because he strikes out, making that stat less relevant. I get that strikeouts aren't the end-all, be-all either, but there is a big difference between striking out 32% of the time in A-ball and striking out 30% of the time in AAA (Phillips this year) and striking out 26% of the time in the majors (Santana this year). Yes, hitters improve, but so do pitchers as you move up in leagues - you have to not just account for the player's age, but also the improvement in level of competition at the next level. This is what I'm getting at with falling in love with one stat and ignoring the big picture. I'm wondering if advanced analytics have gotten to the point where some are falling in love with one or two niche numbers but overlooking the big picture.
