i don't hate Cueto. however, i do feel that he would be a better pitcher in the pen. mainly due to his mental lapses as a starter. as an added bonus his fastball would have a little more mph in the pen as he wouldn't have to pace himself.
as to him being 'average' he is actually a bit below with a career ERA+ of 94 in 67 starts. take a second. 67 starts. and yet IMO he isn't showing improvement. how is he any different than the Johnny Cueto who pitched in May 2008?
