There are going to be lots of potential players available. I mean the Hawks have already said Belinelli and Illyasova are both available for a 2nd round pick (and no long term salary). The Magic are aggressively looking to move Fournier, Hezonja, and Payton. The available players are only going to increase as the season wears on. Not all of those players would obviously help Cleveland, but there will be players available that absolutely could help the Cavs.
For example, maybe Atlanta is willing to move Bazemore. He, would plug a lot of Cleveland's holes as he is a legitimate starting SG that is a + defender and respectable shooter. Not sure either team does it, but Smith + BKN for Bazemore makes a lot of sense for both teams. Obviously other players could be added as necessary (Dedmon seems like a player the Cavs could use).
I think the Cleveland fan forum would light itself on fire if Bazemore was the main get from the Lottery pick. I would be so beyond thrilled if that somehow happened.
Maybe depends on how Bazemore looks for the Cavs and what he does for them, but this isn't a bad trade for Cleveland in a vacuum, especially with the BKN pick looking like 8-10 rather than 1-3. Irving and Smith for Thomas, Bazemore, Crowder, Zizic, 2nd rounder is a fairly even trade all things being considered. May be they just add Frye and Dedmon to the trade making it a little more palatable to Cleveland.
Cavs would have to feel pretty good about their playoff chances if they rolled in with this team
PG - Thomas, Calderon, Rose
SG - Bazemore, Wade, Shumpert
SF - James, Green, Korver, Osman
PF - Love, Crowder
C - Thompson, Dedmon, Zizic
That team should easily come out of the east, and if they ever get Crowder figured out defensively might be able to realistically challenge the Warriors (though I would expect GS to still win). The reality is the Cavs badly need someone like Bazemore. He would just make their whole team better because SG is by far their weakest spot and the spot they could most use a 3-D type player (Bazemore is more talented than a regular 3-D player, but that is his basic skill set).
