OK, clujer, I despise MB more than anyone here but really, a reliever is supposed to have a low ERA. Starters, especially freakin aces, are too, but we all know, love and accept MBs incompetence. Except me of course...
At the same time, it only takes 1 or 2 bad games for a reliever's ERA to skyrocket, and it takes them 2 months to get it back down. Koch had a horrible start of the season, but for the last month he's been solid.
Starters can afford to have a few bad games because they pitch so many innings.
Koch has an era of about 1.15 over his last 15 outings...
