He was 1st in the national league in wRC+, OBP, BA, and he is leading all twins players in hits, doubles, RBIs, runs, SLG, and OPS. So I have some confusion on this argument that he wouldn't generate ANY efficient offense and move the needle.
Also, we could have made some free agency moves or put together a different trade package that would keep Arraez and get a solid rotation guy. We didn't value him. Twins fans have some cognitive dissonance when it comes to Luis Arraez and his value.
