He was hired to build a winning team and probably to set up a system where it can be sustainable.
If you look at what the Rays did after some of their "sell-offs" they actually improved in the short and long terms, and many of the very good players they dealt away had a lot of people scratching their heads, until the guys they traded fell off a cliff shortly afterwards.
Look, I'm not saying Bloom will trade Barnes, or that he will follow the Rays example 100%. He had to do some of those moves for financial reasons. He does not have to do that here, but he did learn some valuable lessons from several of those trades that may carry over to his time, here.
Another factor to think about is how we define "competitiveness."
Is it having an outside shot at a WC slot?
Is it having an inside shot at a WC slot?
Is it having a good chance to win the division?
Is it having a good chance at winning a ring?
I know many of you believe in the playoff crapshoot doctrine, but I don't, and maybe Bloom & Co. don't either.
If they think we have a 10% chance at winning it all, and a trade of Barnes might make it a 2 or 3% chance, but will greatly increase our chances, next year and/or for several years afterwards, maybe they consider it.
If they think our chances are 20-30%, the choice gets much harder, but if you believe in the crapshoot doctrine, nobody ever has a20-25% or higher chance of winning a ring.
