A cautionary tale of a trade you regret. Team A trades it's best SP. A year later, in the throes of a pennant race, Team A trades three prospects for a similar SP. Newly acquired SP starts 4 games for Team A down the stretch before injury and starts 5 games the following year before injury and never plays for Team A again. Team A then trades the previous year's first round draft pick for another similar SP and subsequently trades a the league batting champion for another similar SP. Team A now has a similar SP but doesn't have the three prospects it traded for the first replacement, or the first round pick it traded OR the league batting champion it also traded. But it does have Edouard Julien who can't play defense and JUST MISSED winning a batting championship with his .199 BA.
