By all accounts, Devers is a very hard worker. Mike Lowell had some very nice praise for Devers when working with him during spring training.
The defense hasn't come along as quickly as we'd like, and the hitting seems to have taken a step in the wrong direction, but I really do think we need to have patience with him. He's so young. He has shown that he can hit at every level. The pitchers have adjusted to him and now he needs to adjust back.
As far as defense goes, Adrian Beltre made 29 errors in his first full season with the Dodgers. Once again, Devers is very young. Patience.
