An interesting exercise: 2012 ranking of Cubs' position players by OPS in the National League:
C - 15th
1B - 6th
2B - 13th
3B - 16th
SS - 4th
RF - 7th
CF- 14th
RF - 15th
I am assuming that the first RFer, is actually the LFer, but are those the rankings of PLAYERS, or of the output from the POSITION?
You would expect the output from 3B, CF, SS, 1B and C to all be appreciably better in 2013 than they were in 2012, with 2B and RF likely unchanged (assuming DeJesus plays RF as opposed to CF). LF output is the only one likely to be worse.
