Then I'll take a stab at it. They had comparable FIP's, Samardzija's bWAR and fWAR were lower this season likely due to him being shut down early and the Cubs not wanting him to rack up more innings. Had he pitched a full season he may have been able to come closer to the value Shields put up (possibly more). And the one month Samardzija struggled in June (and was the reason his numbers are as high as they are) was because the team had him experiment with a new pitch that didn't work out at all, so after a month they abandoned it and he went back to being a guy who looked like he could be an ace. He had a 3.09 ERA entering June. After June he had a 5.05 ERA. His ERA from July until the end of his season was 2.58. Samardzija was a stud. One of the biggest reasons people cite Shields as an "ace" is his ability to go deep into ballgames and rack up a lot of innings. I think Shields and Samardzija are very comparable pitchers in that regard. Shields has experience and proven stamina on his side. Samardzija was held back this season though, and he could easily turn into an innings eater with his repertoire. Number of times Samardzija reached the 7th inning or later: 14 (in 28 starts) Number of times Shields reached the 7th inning or later: 18 (in 33 starts) Number of times Samardzija threw 100+ pitches in those 14 starts: 9 Number of times Shields threw 100+ pitches in those 18 starts: 16 Number of times Samardzija threw 110+ pitches in those 9 starts: 4 Number of times Shields threw 110+ pitches in those 16 starts: 9 That was with Samardzija being used conservatively. I think Samardzija could have easily been as desirable an acquisition as James Shields. The only knock against Samardzija that you could say worked against him is the fact he's only been starting for one season. Other than that, all signs point to him being as good, if not better, than James Shields in almost every other regard. Samardzija also had a better K/9 than Shields, which people also cite as a positive for Shields. People think he's a big K guy. He's good, but he's also never had a K/9 of 9.0 or more. His K numbers look bloated because he pitches a lot of innings, when the reality is he technically strikes out less than a batter per inning. His K/9 is still good, but the notion some have that he's a top notch K pitcher is a tiny bit misleading. Shields' K/9 was 17th best in the majors. Samardzija's was 4th. That's my opinion on the two, and why I think you could've easily made a case for Samardzija and Shields being a wash in a deal for Myers.
