In another note, I'm surprised by the Samardzija signing. His career looks very similar to Porcello.
Porcello 4.39 ERA, 96 ERA+, 1.35 WHIP, 2.67 K/BB in the AL
Shark 4.09 ERA, 96 ERA+, 1.27 WHIP, 2.76 K/BB in the NL
In 2015, they both had awful years. ERAs in the 4.90s but they both had career best years in 2014. Porcello trended upward at the end of last year, whereas Shark struggled the whole year.
Shark was worth 90 million and the 19th overall draft pick to the Giants. Porcello is a full 3 years younger.
What does this all mean? Pitching has become extremely extremely expensive.
