I'm not quite sure why everyone keeps saying he is another Tommy Hunter. He is well above Hunter, and has always been well above Hunter.
Hunter: 4.79 ERA 4.95 FIP
Blanton: 4.35 ERA 4.17 FIP 4.18 xFIP
not close if you ask me, and Blanton throws 6.6 innings per start on average which is very good. Also he dominates in August.
So if you can get him for cheap, i'm not so sure why it's such a big deal. He's not close to being as bad as people think.
You're right, I shouldn't have said another Tommy Hunter. Blanton is better than Tommy. Homer prone pitchers do not play well in Camden Yards and that is my overall worry. And I do not want to give up a top 10 prospect for a #5 starter who we keep for 2 months.
