But when you are talking an extension like the original post brought up you HAVE to care about thinks like xFIP, FIP, K/9, BABIP and career numbers. He has pitched well this year, there's not doubt about that, but you have to take things into consideration. The bulk of every statistic out there say he cannot keep up an ERA in the 2.50 range, nor should we expect it, especially, especially when bringing up an extension.
