5x5 roto keeper league.

All these players are eligible to be kept for at least the next 2 seasons.

I get Justin Upton and Desmond Jennings - Upton's only for the next 2 seasons, Jennings for the next 2 with the possibility for an additional 1-5 years.

He gets Curtis Granderson and Michael Pineda - Granderson's eligible for 1-4 years and Pineda's contract is the same as Jennings'.

Should I pull the trigger?

Ok, so I know everyone loves dynasty questions, but i figured I'd give it a shot. I need to keep 4 of the following guys, and I have a pretty good idea of who I'm holding on to, but I wanted to see if I was close with what everyone else thinks.

Casey Kelly

Nick Franklin

Jacob Turner

Brandon Belt

Devin Mesoraco

Simon Castro

Tanner Scheppers

Derek Holland (I know he's not a prospect/rookie anymore but I curious what people think)

Thank you all in advance.

I know everyone hates fantasy stuff on here, and normally I wouldn't ask it, but this one's too close for me to call.

I was offered Neftali Feliz and either Porcello or Buchholz

for Justin Smoak and Jeremy Hellickson

I personally like the deal, because I have some pretty good bats in my farm system, and only 1 good arm. I guess I'm more curious as who to take between Porcello and Buchholz in the deal.

The contracts system is that I would have Porcello or Buchholz for the next 3 years and the other 3 for up to 6 years.

As you are all wise sages I was curious to know what you thought. Thanks all.
