What big piece though? The ones you'd get for that package of expirings can likely be had now, and his name is Zach LaVine, lol. The expiring money might be more valuable to Monte than another team at this point, although it's one year too late perhaps. Now, if Monte's planning on moving Murray at any point and his untouchability isn't that great then that's a whole other thing. Either way, to me, whether Huerter or Barnes are in the trade vs. having space to make the same trade it's the all the same end. Actually, even then the space probably has more value. If they hang onto both Huerter and Barnes, Brown has to start focusing more on them which might mean guys like Murray and Ellis have to take a step back. Expirings by themselves seem to have less value nowadays and teams tend to look for value with it unless they are dumping a complete albatross of a contract. It is what it is. If Monte wants a big fish and not to sacrifice Murray or a pick load in the process, FA is honestly his best shot and maybe even his only shot. Also, that 13th pick would be like any other pick, if the player looks like a star, you won't want to trade him, if he doesn't, no team will really want them. They can be throw ins but once a pick is actually made it gets dicey. Look at Mitchell. 9th pick on draft day vs now, what's the comparitive haul? haha.
The thing to me is that Monte has to start in some direction. Not necessarily a big move, but at least a step in that direction with as many options as possibilities. Planning for potential cap flexibility and cutting loose what appear to be ancillary rotation pieces, ESPECIALLY if Monk is re-signed, would be wise. If Monte runs it back again, and it's another season like the last then that means for sure pieces like Huerter and Barnes lost even more value. Factor them in again, or cut bait, it's that simple.
