My favorite was a guy in one of my leagues using two DHs to platoon C and CF.
Player A: 9 range, 19 glove, 61 arm strength, and 53 accuracy (85 games)
Player B: 10 range, 18 glove, 53 arm strength, 57 accuracy, 67 pitch calling (71 games)
While in CF for Season 47, they combined for 156 games, 61 errors, 15 minus plays. The previous single season record for errors in the league was 29, set way back in Season 9; so they slightly more than doubled the previous record.
While behind the plate they combined for 162 games, 9 errors, 1 minus plays.
But they hit
Player A: .292 avg, 52 hr, 130 rbi
Player B: .292 avg, 29 hr, 91 rbi
