i actually dont think the idea is that bad.....you have to get key guys rest at times, especially a day game after a night game, and many managers try to take 1 guy out a game, and u end up with a shuffled lineup for 3-4 games trying to get diff guys rest....and u are weaker in all 4 games...this way, you are real weak in (1) game (just pray you can win) and you are back at full strength the next day...
Dusty makes his mistakes, but i dont really think this method is that bad
