The only thing you expect less than the Spanish Inquisition is a September trade in the NBA, to say nothing of rare last-second October deals like the one that brought James Harden to Houston a year ago.
There are good reasons for the holding pattern in which teams find themselves once the leaves start changing.
On the brink of training camps, only the most no-brained trade scenarios make general managers think twice about staying put. Those camps are the best way for coaches to distinguish between what they actually have on hand and what's still needed, information that's absolutely critical to GMs who know the difference between team-building and fantasy basketball.
Even when a player's days are numbered, any number of factors may impact timing, and very rarely does that mean wheeling and dealing on the heels of the draft and height of free agency.
All the same, some guys' days are more than numbered. They're borderline endangered. Those are the ones who could defy conventional wisdom and start packing their bags early.
