A lot of this just goes on how you read De Leon. I tend toward pessimism on him, always have, but if you think he's a Berrios-type, the Mejia comp doesn't work as well. If you think he's toward the back of a top 100 list, plus the sore shoulder, plus the age, plus the durability concerns it's not quite as out of whack as Nick suggested. De Leon is still a better prospect (fangraphs guy put a 55 FV on him to Mejia's 45 but also seems more sure of Mejia's future) but the odds of him having a better ML career than Mejia (lower ceiling, higher floor in that he's durable) is probably closer than some want to admit.
