You see only what you want to see and make the "sophomore slump" excuse.
Cave's second year was actually his best year so the Soph. Slump is bs. Caves defense was average at best , Julien is a black whole to the defense. Has been and always will be.
Going by 2 complete years; with as little faith as I put in WAR, Cave's WAR was 2.2,; Juliens was 2.4.
Cave went steadily down hill till last year when he had his 3rd best year; Julien will, if he is fortunate do as well as Cave did, but will never be as good with a glove..
