Here are some outfielders that should outperform their price, based on ESPN average draft position (ADP). Based on a 5 x 5 redraft league.
Player (ESPN ADP):
Nick Markakis (137) - better lineup this year. Unsexy but valuable, and if he adds a few HR you're golden.
Rajai Davis (143) - comparable stats to Juan Pierre, Michael Bourn, or Brett Gardner, but 30 picks later.
Travis Snider (180) - 30 HR, 10 SB upside
Jason Kubel (208) - expect slight BA rebound. Can bench vs lefties
Jose Tabata (217) - a little young but upside
Dexter Fowler (226) - a little young but upside
Julio Borbon (227) - slated to start in CF, speed to burn
Coco Crisp (230)
Seth Smith (237) - Hawpe is gone. More PT. Can bench vs lefties
Will Venable (260) - power/speed upside for deep leagues
Peter Bourjos (260) - should get you 10 HR, 20 SB. Glove will keep him in the lineup
Michael Brantley (260)
Alex Gordon (260) - someday he'll be productive. Too bad it won't be at 3B
