I'd say get yourself a Sutter or Murray and join in.
He does state in his initial post he has done the super reliever himself. We probably all have because it is a winning strategy. But I agree with sneaky snake that there should be limits.
To me it is either a flaw in the ratings (R? rating too high)
or it is a flaw in the rules that allow a guy to throw multiple innings in 2 of every 3 games
or it is a flaw in the game code that does not properly fatigue overused pitchers
or card is underpriced since it is priced like a reliever but delivers value of a 300 inning starter (if value is same price should be same).
Strato should address this. But until they do only someone playing with a short deck would not employ some form of this strategy.
