That's the reason Klentak won't make any major moves this winter, a 73 win team can't be turned into a 93 win team (that's different from say an 85 win team that won 73 games due to injuries and key players having offseasons).
For him, this is year two of the rebuild, and the focus remains on patching holes (with short-term deals or low cost trades for expiring contracts) and adding assets.
This is why anytime a rumor mentions a young player I'm skeptical, because you don't want to rearrange the deck chairs on the Titantic, it has to be a deal that really makes sense - that is, trading one hole to fill another is a waste of time.
Right now they don't really have surplus talent in the organization, prospects are just that until they hit the majors and show they belong, Asche was a bright young prospect until after 1000 PA he looks like an AAAA player. Eflin, Thompson, Asher could be solid young pitchers or flashes in the pan.
The thing with most prospects is they have limited trade value until they perform, no one is going to give you a blue chip for Cozens or Hoskins or whomever. You could get one for Crawford, but that would be somewhat pointless. Even Alfaro needs to hit in AAA to have top value, no one trusts Reading statistics.
The guys who get you a big return are young ML players with proven track records, Hamels (not so young but very proven), Giles.
Guys like Franco, Rupp, Hernandez, Galvis and Herrera are buyer beware, none have put together say two 3-4 WAR seasons. Herrera is the closest. And none is a 22 year old blue chip talent with a huge upside, Franco is the closest but last season raised questions of coachability as a hitter. So buyers are going to be rightfully skeptical. Their potential value next year could be much greater or a little less (because they don't have that far to fall).
And the guys who can usually get you a big haul are the guys you don't want to trade, say Nola if the elbow checks out. But you won't get a huge haul for Velasquez right now, if he starts 30 games with a FIP under 4.00 next year and shows some progress with his command and his secondary pitchers, he'd jump in value because he'd be a potential #1. But in that case why would you deal him (only if say Eflin blew out the joint and Nola was healthy and Eickhoff starts looking like Kluber).
This doesn't mean Klentak won't make moves, rather, he's in the Hinkie position, he doesn't have to worry about winning in 2017, and probably not 2018, so he doesn't feel the urgency to say break the bank to get a corner outfielder who can hit 30 HR or a true closer. So he'll listen to all offers, but it'll be a Giles situation, you have to overpay or the deal won't get done.
