Possible guys to buy low on that were drafted top 30 that have really struggled: Matt Kemp, Giancarlo Stanton, Buster Posey, and Jason Heyward. All guys who should turn it around very soon IMO.
Possible sell high guys: John Buck, Chris Davis, Jed Lowrie. Obviously depends on who you can get in return for these guys but not sure they can all keep up what they are doing at the moment.
