If the Reds are going to trade an 'everyday-player' for pitching, Kearns would be my choice. Denorfia would provide better range in RF and, based on scouting reports, his arm isn't anything to sneeze at either.
I just don't think that the offense would suffer that big of a hit if Kearns was replaced by Deno.
Kearns is on pace to hit 30 hrs. and his D is solid.
What caliber of ML-pitching could he fetch, either alone or packaged with someone else?
