Meh. That's why Wins are useless. Randy Johnson goes 17-11 with 5.49 RA in 2006 and Kip Wells goes 8-18 with 5.74 RA in 2005.
He was bad in 2005 largely because of his 132/99 K/BB. I could see that improving back to 2/1 or so (2002, 2003) and him having a pretty productive season, especially now that he is healthy and under Duncan's tutelage. His stuff looks just great, just looking for him to get that command back to where it needs to be, as others have said in this thread.
