Arrieta, Davis and Lackey all mattered. Arrieta was terrific and will almost certainly be replaced by a lesser pitcher. Davis was great and although maybe a little easier to replace, lots of quality front offices have rolled the dice on the wrong guy in that situation. Lackey's value is under appreciated, as it costs a lot of money to simply get a guy you can reasonably expect to duplicate what he did. It's going to take a lot of work to replace those guys, and they may not collectively improve on that group, so they'll need to other three starters to at least not take a step back. it's a legit big ask. Id agree with you on Arrieta and Davis, but Lackeys only true value came in filling up a jersey with flesh and bones
