Not sure about Meatball, but certainly Chimp, on for a stint and off, no resting on the field. His goal kicking ain't great and he's not that fast that he'll run down players.Alternatively i see Cotch and Prestia getting more bench time.
Say they did 65% each instead of 80%
Nearly 20 minutes less ground time each game.
Extend careers and allow them to play more burst /high intensity
