Ppl here keep stating you cant use the TE you receive from another team, to use in a future trade situation. Yet thats what happened with TE we received from the nets that was used fto get zeller etc. From the cavs.
Then why could the cavs not combine the TE with haywoods non guarantee, instead going through yesterdays trade and giving up 2nds?
Is it that TE(obtained from a trade) cant be combined with non guarantees but can be combined with a guarantee contract?
Where is Roy?
First of all, this stuff is very confusing, so don't let people get down on you for not understanding it. I'd say that 95+% of basketball fans don't understand all of the nuances.
To put this as simply as I can, a trade exception is created in certain circumstances when trades don't "match" in terms of salary. For instance, if a team trades $5 million in salary, and doesn't take any salary back, they're granted a $5 million trade exception. Think of it like a fictional accounting type of thing.
That trade exception lasts for one year. You can use the exception all at once (to take back a player earning up to the amount of the exception, plus $100k), or you can use it on multiple players at different times. For instance, if a team trades for a $2 million player and then a week later trades for a $3 million player, that works, because the team didn't exceed the amount of the original exception.
When people talk about the limitations on a trade exception, they're usually talking about using the trade exception in combination with other assets. You can't trade a trade exception to take back salary that is more than the amount of the exception.
For instance, you CAN'T make the following trade: $8 million player for $5 million TE and $3 million TE. You CAN'T make the following trade: $8 million player for $5 million TE and $3 million trade exception. You CAN make the following trade: $8 million player for (or rather, absorbed into) $9 million TE. You CAN make the following trade: $8 million player absorbed into $9 million trade exception plus #1 draft pick.
Here's where it gets more complicated: trades can be structured in different ways to take advantage of the trade exception. For instance, if a team wanted to trade two players making a combined $6 million to a team with a $5 million trade exception, they couldn't do that. However, they could trade a $5 million player and a $1 million player, if the receiving team was also including a guy making $1 million. It would technically be two different trades: the $5 million player for the $5 million trade exception, and the $1 million player for the other team's $1 million player. It would be reported as one trade, but technically it would be two.
Another thing you'll hear is that trade exceptions can't be traded, which is technically true. Teams don't trade their exceptions; rather, a new exception (with a new expiration date) is included whenever there's a salary imbalance.
In the case of Bogans, here's basically how it breaks down:
Celtics perspective: this is multiple trades. They're allowed to take back all the minimum contracts without sending back any salary to Cleveland, due to CBA rules. They still need to account for John Lucas salary, either by absorbing that or by using him in a trade exception already on the books (since non-minimum deals require salary matching, either through contracts or a suitable exception).
So, trade 1: Thomas salary (minimum) for nothing
trade 2: Murphy salary (minimum) for nothing
trade 3: Powell salary (minimum) for nothing
trade 4: Lucas salary ($1.6 million) for nothing (if using a trade exception) or for Keith Bogans' contract (if not using a trade exception
trade 5 (potentially): Keith Bogans for nothing
So, if the Celtics went the route of absorbing Lucas with a trade exception, that means we would have sent out Bogans for nothing. A trade exception would be created for the salary difference: $5.285 million - $0 = $5.285 million. So, in that case, it would be a $5.285 million trade exception, that we'd have to use within one year.
If we didn't use a trade exception to acquire Lucas, then we'd have to account for Lucas' salary. Thus, the trade would be $5.285 million (Bogans) for $1.6 million (Lucas). The difference there is $3.685 million, and that's the amount of the exception that would be created.
That's probably the best I can explain it without writing a book. I'm speaking in generalities here, and there are a lot of rules about what "matching" actually means in a trade. But that's the (very confusing) gist of it.
Also, to answer your other question: both guaranteed contracts and non-guaranteed contracts can be combined with each other to facilitate trades (with certain restrictions).
