There was definitely some value that wound up going the other way in those deals although it's interesting that out of all those guys, besides Syndergaard, Yunel provided the most value. Most of the other guys providing value are back end pitchers.
I think Henderson Alvarez' career as an MLB pitcher is likely over. It's been three years, which is a pity because I liked him a lot.
Also I just looked Marisnick's stats this year. He has somehow managed to strike out in 47% of his AB's.
