My issue with Bush is the pretty clear downward trend in his peripherals. xFIP has gone - 3.76, 4.36, 4.67, 4.79, 4.98. He has gotten worse 4 years in a row now. His K/9 has slipped under 6 and he is walking more than 3 per 9 now and his ground ball rates have gone down. This is not the type of pitcher you want to sign at all, you are just hoping he has some luck with ERA each year. Back in 2006/2007 I thought he could be a pretty effective #3 but all of his peripherals have taken a dive since then and now he is lucky to be a #4.
