Omar doesn't factor into the roster crunch as Turner didn't play SS. or couldn't. or they felt he couldn't. They believed in Flores. Hell, Campbell had a 149 wRC+ in Vegas, 3x the walkrate as Turner, and was younger. Campbell ended up giving them in 2014 almost exactly what they got from Turner in 2013. There's plenty of reason to think that the Mets saw them as fairly interchangable. And sure, Turner was better in 2014, but it was mostly a BABIP driven increase. He started driving the ball harder, but he was getting lucky too. It doesn't seem unreasonable to think some time within a different system working on different things helped him become what he is now (and a juiced ball, certainly) I'm not saying that personal feelings didn't enter into it, but he was understandably a guy on the fringe of the roster. It's not like he was a 3 win player and Jeff was like 'I hate him, get him out of here' He hadn't, and wasn't, adding much value. He was completely expendable, and he was already 30.
