but then where is their offensive upgrade coming from? If they resign Ross and presumably offer arbitration to Schierholtz, we're looking at an outfield of Belt, Ross, Schierholtz with Pill and maybe Torres as backups.

So either they sign Rollins at SS or sign Cuddyer or Beltran and rotate Belt, Ross, Schierholtz.

SS Rollins
2B Sanchez
3B Sandoval
C Posey
LF Belt
CF Ross
1B Huff
RF Schierholtz
