I can't imagine having the best defense in baseball with Yelich in LF, Hiura at 1B, a position he has never played, and Narvaez at catcher. That doesn't scream "best" to me. Have we improved from last year defensively? Yes, assuming Cain hasn't lost a step. I don't really put Shaw into the category of an elite defender. Have we improved offensively? Probably, assuming Yelich and Hiura's acts last year won't be repeated. Shaw is a wild card. We have no idea where he will be offensively. We still have Arcia unless Urias overtakes him. What teams will be better defensively if they sign JBJ?
