Keeper Help

[Lofaw]

10 team 5x5 Roto Keeper league. We can keep 4 players drafted after the 3rd Rd or that had been kept the previous year. Players can be kept for 5 years. We also can keep 2 minor league players.

One other thing it's a 2 Catcher league. Last season I came in 2nd place.

Here are my choices: (with last year I can keep the player)

Carlos Santana (2014)
Salvador Perez (2015)
Paul Goldschmidt (2016)
Aramis Rameriz (2016)
Desmond Jennings (2016)
Adam Jones (2016)
Jason Heyward (2016)

Lance Lynn (2016)
Jarrod Parker (2016)
Kris Medlen (2016)
Justin Verlander (2013)

Because we start 2 Catchers I pretty much have to keep Santana and Perez. So that leaves me with 2 other keeper slots. It's pretty much between Heyward, Jones, & Verlander, Right? Verlander would generally be a lock, but the fact this is the last season I can keep him when I can keep the other 2 possibles for another 4 years after this year changes things.

I also can try to trade for an extra Keeper slot as Keeper Slots are tradable, but it's not very easy obtaining any. How high a draft pick would it be worth it for me to offer someone for a Keeper Slot to keep have enough Slots to keep all 3? I'm going to try to Rameriz, Goldschmidt, or Jennngs to pick up a slot, but I'm guessing it's more likely going to take a draft pick and even that might not get me the slot I need.

Which brings me to my 2 Minor League Keeper slots. Which of these should I keep with my 2 slots:

Jonathon Singleton
Mike Olt
Oscar Taveras

Dylan Bundy
Gerrit Cole

I was thinking Taveras and Bundy? Although Mike Olt and Cole might help my team this season. Thoughts?

Please help. I need to make a decision soon. I'm going to look over the other teams to see who would be best suited to get a Keeper slot from.
