For one, I don't place total value on a player based on one good year of defense.
I also don't value a player with one year as highly as one with 2, 3 or more.
Yes, his OPS is .790. You act like 7th best is something we need to cling to.
Again, I am not "for" trading Dugo, and I'm 200% against DUMPING him. I think Rafaela is a better defender. I think Duvall and Abreu may not be the downgrade on defense in RF, you seem to envision, and no, I don't use BR's dWAR to measure a player's value on D.
I've already discussed how our defense should improve without needing to add anyone from outside the system, but I do see trading Dugo, among several other choices as a possible player we could trade in a package and try to improve our pitching- an area we both agree needs serious fixing.
If we have to lose a little ground in RF to gain a lot of ground with teh staff, you'll say "It's not good enough.?".
