If we get Tanaka and keep Shark, I challenge you to explain how it could possibly be worse. We lose little from the offense and should get better without adding much from the outside. Starlin and Rizzo should rebound/improve, and we likely get 1/2 a season of Baez and other incremental gains. The bullpen is a lot stronger than it was to start last year. The rotation has taken a hit, for certain. But adding Tanaka would make up that gap pretty easily. If, and it is a big honking if, we add Tanaka, I believe we'll get to see interesting baseball in the late summer in a while. I'll be stunned if they get Tanaka. I don't think it's realistic to expect they land him; I hope I'm wrong, but I doubt it. The offense was just rank last year, and they haven't don't much to improve it. It's basically hinged on praying that Castro and Rizzo rebound and that Baez both shows up and is good. Those are some pretty big if's; I really like Baez, but it's hardly unlikely that he shows up and struggles. The offense wasn't quite as bad as the runs scored would lead you to believe. The wOBA was still bad, but was within shouting distance of average. If we can: - manage to avoid giving Barney 555 PA's of .252 wOBA - have Castro improve on his 705 PA's of .280 wOBA That alone will help improve the performance dramatically. Also, it is often pointed out that we are not likely to get repeat performances from the Murphy's of the world, but we are also not likely to get Lillibridged in 2014, either. The 286 PA we got from Lillibridge, Clevenger, Watkins, Borbon, Sappelt and Alberto Gonzalez contributed greatly to the lousy performance. Simply having a deeper bench would avoid a lot of negative performances. We'll still get some bad results from some guys, but avoiding the incredibly negative results would make things a lot better. Without any additional changes, I strongly doubt the offense will be top 10 in MLB. However, it wouldn't surprise me that much if they were very close to average in most offensive metrics - especially in the NL. But at the same time it wouldn't take much for it to stink. Obviously we want it to do well, but they're yet again setting up a team where things have to break right just for them to be OK.
