Bad relievers and terrible, incompetent closers who are also defined as being part of the larger pitching staff. Baseball, like football, is situational and a great starting pitcher who has a 2-0 lead going into the 8th inning also 80-95% of the time needs more runs as a cushion to ensure his good day stands or isn't forked up by a inept, mediocre set of relievers/closers.
