Bullpens are obviously a major part of the game and knowing how good a teams bullpen is crucial in handicapping. Their are rankings of bullpens out their by ERA and whip but these numbers don't tell the whole story. For example Mets are #11 in terms of lowest Bullpen era but obviously the Mets bullpen isn't even top 15 in the league right now. Whether its injuries or guys getting moved to the bullpen from a starting role. Anyone know any sites that rank bullpens based on a variation of stats, or does anyone wanna rank it themselves?
