You'd be replacing EJax who's going to have a 3+ ERA over 200 innings with someone who's likely not going to come close to those numbers.
By losing your #4, you shift your #5 to #4 and then you have to use a guy that couldn't crack the rotation this year in the 5 slot. I don't think it takes a huge leap of faith to say the rotation will likely perform worse in 2013 than it has in 2012.
And that's not to say that the 2013 rotation won't be great... it likely will... but it won't be WS winning caliber as I believe the 2012 staff is.
Detwiler has an ERA of 3.02 and Edwin Jackson is 3.57. I think ERA is not all telling, but that is a big difference. Ross Detwiler is coming a 3.00 ERA year and Edwin Jackson is having the year of his life. Detwiler should never have left the rotation this year except the team is overly enamored by CMW.
Detwiler is cracking out his second good season in a row. At what point do people stop acting like he and his ERA are a mirage? He'd be a #2/3 on most teams. A really good one.
