While I'm still unwilling to say we're "out" on Moncada, my feeling now is that we're more likely to target Andy Ibanez or several of the other YOUNGER players that have been (or will soon be) cleared to sign.
I agree with those that say that Olivera's by far the player likely to make the quickest impact, but the more you think about it, the less sense he makes. He's likely to get something in the 3-4 year/$30-$40 million neighborhood. He plays positions we have both current (CJ/Callaspo/KJ/Peterson at 3B, Callaspo/KJ/Peterson/EY Jr. at 2B) and hopefully future (Ruiz/Peterson at 3B, Peraza/Peterson at 2B) answers for that should be ready by the time the new park opens.
Everybody still questions the similar Markakis signing, but at the time it actually made sense - the decision to blow it up and start from scratch hadn't yet been made (at least publicly). Had we kept and tried to extend J-Up, Markakis was by far the best available option to replace Heyward if we were going to try to contend. At that point the rotation was all but set (Teheran/Wood/Miller/Minor/Hale or veteran signing), and all the other pieces were still in place. IF we were going to make a run, that signing made A LOT of sense. Bounce backs (to some extent) from CJ, Simmons, and anything from B. J. with Markakis replacing Heyward's offense would've arguably made the team better than before when you replaced Harang with Miller.
Fast-forward to today. Another signing that would make an immediate impact (at a position we don't "need" a replacement before 2017) makes precious little sense - IF Hart & Company believe that Peraza is the answer at 2B or CF. If you expect Peraza to be sitting atop the order when the new park opens, signing Moncada or Ibanez is a much better approach. You'd have control over either (at much younger ages) for far longer.
Olivera would be 31 and under contract for 1-2 seasons when the new park opens. There have always been questions surrounding his true age, and his health has been an issue of late. Much like Markakis, the money he'd be making isn't the issue - both would be great pieces for a contender. Of course, we're not going to be one of those before 2017 at the earliest barring some significant strides from Ruiz and a couple Pitchers AND the addition of J-Up or Cespedes next winter. I do think someone will come calling for Markakis when a need arises for them between now and the end of his deal, but we'd also be looking for the same thing to happen with Olivera - AND hoping both would remain healthy and productive.
I have no doubt we're going to make a splash with a Cuban signing pretty soon depending on who becomes eligible to sign and when, but if we don't go get Moncada I'm becoming more convinced every day that the player(s) we sign will be 23 or younger.
