What does it all mean?
The Tacoma Pixies are a breed unto themselves. Their bullpen averages 6.26 IP/G and accounts for 76.3% of its decisions. This, of course, has to do with how the staff is setup to leverage the great Donnie Brown.
The bullpens of two teams in particular are severely hurting their teams' chances. The Tampa Bay Fighting Hamsters and the Seattle Mariners both have bullpen ERAs that are more than 6 runs worse than their rotation. Most of this problem has to do with the fact the average fatigue of their bullpen when entering a game is 53 & 36, respectively.
Aside from those two aspects, the data definitely shows the strengths and weaknesses of each club's pitching staff. Only 9 teams have a better bullpen ERA than their starting rotation. The average rotation goes about 5 2/3 IP per game with an ERA of 4.90. The average bullpen goes about 3 1/3 IP per game with an ERA of 5.60.
Since this was my initial post, it was a learning experience getting tables to format properly. As a result, the analysis was a little weak. Next time around, it will be stronger.
By the way, if you click on the charts, you'll get a more readable format.
Enjoy.
