H2H Points Keepers

I get to keep 5 players per season. Players may be kept for a maximum of two consecutive off-seasons, and then are forced back into the Draft Pool. All players listed are eligible to be kept for both the 2015 and 2016 seasons, except those listed in red, who can only be kept for 2015, and then would need to go back into the Draft Pool. I don't have to commit to them for 2 years, but if I have them at the end of the 2015 season, they are eligible to be kept again. Which 5 make the cut?

C/1B - Carlos Santana, 3.5 PPG, #1 C
SS/2B - Dee Gordon, 3.7 PPG, #1 SS
SS - Hanley Ramirez, 3.5 PPG, #9 SS
OF - Kole Calhoun, 3.5 PPG

SP - Hisashi Iwakuma, 15.1 PPG
SP - Ervin Santana, 13.8 PPG
RP - Wade Davis, 4.5 PPG
SP - Matt Harvey, 19.3 PPG in 2013
SP - Jason Hammel, 12.8 PPG
SP - Phil Hughes, 15.4 PPG
SP - Matt Shoemaker, 13.3 PPG
SP - Carlos Carrasco, 8.1 PPG (21.9 PPG as a Starter)
SP - Andrew Heaney, 3.1 PPG
SP - Jesse Hahn, 13.1 PPG
SP - Ian P. Kennedy, 13.7 PPG


My initial thought is to keep Hanley, Harvey, Carrasco, Iwakuma, and maybe Santana? That way I can spend my first several picks on big bats, and then sharp for bargain pitching to round out my rotation later. Do I consider Gordon? I'm worried about massive regression potential. Do I gamble on Heaney?
