Both Meche and Chacin have bloated ERA's, but I think Chacin has a better upside. He battled though injuries last year. Don't get me wrong, Chacin has a lot of work to do, but I think he still can be a consistant 12-14 win pitcher or even better. Meche has had an easier schedule pitching out west and his ERA remains well above 4.40. It really doesn't matter since the Jays haven't signed another pitcher yet.
