Was talking at the deadline, not last free agency. Regardless, what Memphis did using theirs for Iggy + 1st is a rarity in that the Warriors were desperate to get something for a departing Kevin Durant. They had to dump salary to take on Russell, otherwise they would have paid massive tax penalties. They ultimately traded spots in the draft and got Wiggins for KD. That kind of deal doesn't occur at the deadline often. Lots of teams are upset they didn't make that trade.
With TJ Warren, that kind of deal doesn't get done at the deadline either.
You can be upset about something that happened 7 months ago, but any beneficial deal with the TPE or Lee would've had to be done last off-season, because they're cost cutting or cap reducing measures for the receiving team and this free agency period isn't going to be very good and teams had already made their moves to reduce cap penalties. Any moves that stretched salary beyond 2021 would have impacted the Mavs' ability to make moves that genuinely make this team substantially better.
In short, there is no urgency in the league right now to dump salary, it's exactly why Drummond went for peanuts.
Can you really be upset with what the Mavs FO has done over the last 2 1/2 years? They have to go 10-21 to have a .500 record and be what people thought they were going to be going into the season. That's with KP missing 12 games and Luka missing 8.
I wouldn't expect them to do much this free agency period other than drafting their guy and using their exception. In fact I would be surprised to see any big moves between now and the 2021 free agency period.
