Monday is more than just the deadline for each team to reduce its roster to 15 players.
The day before the regular season starts is also the deadline to extend -- or not extend -- first-round draft picks in the last year of their rookie contracts.
By 6 p.m. ET on Monday, we will know if, for instance, Jaylen Brown and Buddy Hield will be under long-term contract.
In all, 16 such players are eligible to extend their current contracts.
Here are the key players and why their deals will -- or will not -- get done by Monday. We also look at the roster decisions teams will face before games tip on Tuesday.
