MAVS NEWS:

[F Gump]

Right, thanks...let me ask the question a different way. Are the "camp bodies" getting contracts that are less official, and almost setup for them not to make the team?

They are official, but add some extras. They include an Exhibit 9, 10, or both in the contract. Nothing is guaranteed, even if they get hurt. When ("if") waived, they'll get a bonus (as well as GL pay) to play for Mavs GL team. And in the CBA accounting, such deals explicitly are not to be included in Team Salary until the regular season.

CBA FAQ explanation is a bit dated, but offers the gist of things.

A player signing such a deal does not expect he will be on the 15-man NBA roster when the season begins, nor does the team signing him, although the contract makes no exclusion of the possibility.

If you want to see, you can look up an online copy of the CBA, which has a standard contract as an addendum, and the possible exhibits are part of that.
