I think you have to offer Duvall and Joc the option. I doubt both take it. Since Snit won't play Joc everyday, I'm not sure he wants to stay. We need OF and I feel like both guys are basically guaranteed to out perform those deals. The opportunity cost is that you are tying up money in OK players and not getting impact bats. I know Duvall is going to be a 3 WAR guy this year, but I'm not calling him impact.
The question is, who are they going to get? Is Blackmon going to opt out, be an impact guy and sign with the braves? I think no to all 3. If you had Joc and Duvall, would that stop you from getting Marte? I don't think it's enough money to stop us or years. Just unlikely we are the high bidder on Marte. Castellanos will want more than we'll pay. Conforto may be an option, but his production causes some concern.
As an aside, how many teams have 3 WAR players hitting 7th or 8th???
