mmm... I think they are very different animals Pal. MB had several years with very solid ERA numbers below 4.
2001 3.29
2002 3.58
2004 3.89
2005 3.12
2007 3.63
2008 3.79
2009 3.84
2011 3.59
2012 3.74
...and last year he posted a very solid ERA, 3.39. Seems like we weren't wrong in wanting him.
Here's a very solid track record and a tendency for a true No. 2-3.
On the other hand when you see Porcello's numbers, aside 2013, they are garbage.
2010 4.92
2011 4.75
2012 4.59
2013 4.32
Those are No 5-7 numbers.
My take in this signing is that they do not want to s*** the bed like they did with Lester, but cmon, this is Rick f***ing Porcello we are talking about, sure a young but unproved pitcher. If you want to overpay a young guy like José Fernandez, Kershaw, Teheran, etc. it is understandable, but again, this guy has to prove at least two more years that 2013 was not a fluke year (I tend to think this) in order to earn this kind of money.
They basically based this signing in one year, oh and because he is young. As I said, I do not see a 5 ERA pitcher as he once was, but I do not see a 3.5 ERA pitcher either. IMO He is going to be no more than a 4.0 ERA pitcher (No. 4 type), reason why I think this contract is terrible (spanish haha).
