In the end, What's the worse contract? (Obviously the last two are just "educated" guesses)
Melancon for 62
Jansen for ~80-85+
Chapman for ~90-100
Chapman has been consistently near-dominant, so from a risk standpoint he's pretty solid. But you don't pay a closer 100 mil. Jansen has been almost as good, but he strikes me as a type who will drop off out of nowhere. And Melancon could easily just fall through the cracks without the tutelage of arguably the best pitching coach in baseball.
So to answer your question, I have no f***ing clue.
As for pitching coach coach, Giants are pretty damn solid with Dave Righetti. Can't say I'm familiar with who he was with in his previous stops, but it's probably close to a wash.
I personally like it. Yeah, it's a lot of money, but it absolutely needed to be done. They couldn't continue with Romo or Casilla. And their in-house options bombed last year. I had hopes for Strickland and Osich but that's long gone. Maybe Derek Law, but he isn't ready. No faith in Will Smith.
A tweet I saw summed it all up.
"Melancon has blown 10 saves over the last three seasons. The Giants blew 9 in September alone"
Jesus. I mean, the Sox aren't gonna have a farm system left....but that rotation is gonna be nasty
Assuming Porcello doesn't regress to the mean. The dude was 9-15 with a 4.92 ERA in 2015. He had been the definition of a 50-50 pitcher.
I don't think anyone's expecting Rick Porcello to maintain his 2016 pace going into 2017 but I don't expect him to fall off a cliff, either. Remember, he's still only 27 years old.
I wouldn't be surprised to see his 2017 numbers be a middle ground between the bad of 2015 and the good of 2016, so something in the neighborhood of 15-9 with a 4.03 ERA, 1.18 WHIP, and 169 Ks in 197 IP. That's not pitching like an ace or a Cy Young winner by any means, but it's more than good enough to be a third starter on a championship contender, which is all he'll really be asked to be with the acquisition of Chris Sale and the expected "year two in Boston" rebound season for David Price.
