Should I pick up any of these players for my fantasy team?

Do not drop gardner, he is doing amazing and has the potential to get 50+ steals. Also, because ellsbury is out, he will get you lesser steals this year, try trading him to fill your third base hole. (david freese isn't a really great long-term option.) I don't really think you should add anyone but if you really want to, add furcal cause lance berkman isn't the same anymore and is struggling and you said you want some players that play a postion other than outfield cause you already have 6.
