How can I Improve my fantasy baseball team?

First of all, I don't see that Davis is weak at 3B. He hit 17 HR's last year in only 295 AB's. That is better than average at a thin position. I do agree that Cano is average and may never be better. Find a young guy like Mike Fontenot. Too bad that Greene isn't a better BA hitter. You wouldn't have to make any moves if he were but he isn't. Pretty good outfield. You have two RP's that aren't closers. I never keep a RP that isn't a closer. Wait until Marmol doesn't get the job before you make any moves about him. Perez already lost his job to Motte. You have a lot of SP's. If your league has an inning limit on pitchers, you have too many of them. If not, then it doesn't matter. You have a lot of young talent that may be sleepers. With a 25 man roster, it's fun to sit on them and wait and see. I see 2B as your biggest hole.
