Given what I am seeing in your draft, I doubt that Ackley would fall to you at 5.
Here's how I rank them for this year, with my projected numbers.
Freeman - 550 PA, .270 AVG, 15+ HR, 5+ SB
Morel - 475 PA, .270 AVG, 10+ HR, 10+ SB
Kimbrell - 50 IP, 60 K, 3.40 ERA, 1.40 WHIP, potential closer
Minor - 150 IP, 150 K, 4.25 ERA, 1.40 WHIP
Espinosa - 525 PA, .240 AVG, 15+ HR, 10+ SB
Given my ranking of them for this year, you lose nothing by throwing him back in. At worst case, he'll likely be available to you again this year.
BTW, long term value I rank them like this:
I just don't like Espinosa's bat.
In my fridge: Founders Kentucky Breakfast Stout (KBS), Central Waters Peruvian Morning, Bell's Batch 10,000, Dale's Pale Ale, Capital Brewery Amber, New Glarus Moon Man, and Guinness.
