It seems to me that he would make the Reds pitching even better.
I think that he would push Phillips to be even better, and that Phillips could play short better than Keppinger or the aging Gonzalez. Though RF, LF, and 3B are the Reds biggest fielding problem areas according to the split stats at ESPN. I just don't think that the Reds would lose anything by moving Encarcion to 1B, Keppinger to 3B, and Votto to LF. Leaving Jay Bruce for RF or CF and finding the upgrade replacement in the other open position.
"if" Griffey and Dunn left the team.
