I think the Denorfia backlash is a little out of hand.
The prevailing opinion at the time was that Denorfia was a good bet to be a league average center fielder with the bat, cheap, and more than adequate defensively. I wish the Reds had taken the opportunity to play him to find out if he could handle a full season.
Currently he is hitting 283/365/326/691. I'd take that 365 OBP% in the leadoff slot, his defense in CF, and his $400K salary. (Provided the Reds had given him the opportunity to prove he could handle it.)
