Rafaela is on pace for about a 2.5 Fwar season, mostly tied to his defense but that alone makes him a valuable player.
I don't think he's ever going to be an offensive stud, but I've always hoped he could take enough steps forward to not be a complete black hole in the lineup and you feel fine about him hitting 8th 9th.
It's early, the sample size is small, but the K% is down from 26.4 to 18.9% the BB rate is up to 6.8% he's actually making a little bit more contact this year, but his BABIP is lower around .250% but overall he's still chasing way way way too much.
I think there's enough there, underlying to see a guy who can take steps forward and be a .650-.700 OPS guy, but the approach is not there, and there's not enough power to overcome the approach to ever be much more than that.
I really really really like Rafaela a lot, but I never understood the extension. Guys with his profile just aren't well paid in arbitration, and his skill set probably does not age well once he losses a step.
