Thank you for supporting your view with some numbers, but I still don't find that terribly persuasive.Chang has a 29% K rate in his time in the bigs, and 26% at AAA. (Iglesias career 12%, Andrus 14%). Exit velocity is great but you have to make contact first; not sure that he will make enough contact to be useful.
xWOBA includes strikeouts. So Chang's batting profile, including walks and Ks, has been, BABIP aside, as valuable as Andrus' and more considerably more valuable than Iglesias' over the last few years. And he's, you know, six or seven years younger.
xWOBACON is the statcast stat that excludes walks and Ks. That measure effectively ignores Chang's biggest weakness, and as a result he looks wildly better by that measure: .363 (a tic shy of league average) for Chang vs. .323 for Andrus or .300 for Iglesias.
(Mondesí has a .392 career xWOBACON, which is marvelous. José Ramírez is at .393. Mookie Betts is at .399.)
