that's not really true. his xFIP's with the twins were 4.45, 3.94, 4.81 and 4.54. he was pretty close to league average in 2004 and 2007, above average in 2005 and below average in 2006. it wasn't until he got to seattle that he became truly terrible. It's mainly those WHIPs scaring the crap out of me. That and the concept that Silva is so damn hittable that xFIP doesn't accurately judge what he brings to the table
