Not every move Vlade made was bad. That was a straight salary dump for Dallas so they could go after Porzingis in the off-season (which hasn't really worked out for them) but I still credit Vlade for making the deal happen at a time when most people saw Barnes' contract as a deal breaker. Those types of deals aren't available every trade deadline though.
I think if you look at where we were a month ago, going out to get some defensive roleplayers without losing any key rotation guys makes a lot of sense. And when all Monte gave up in return was a few essentially meaningless second-round picks, I don't see anything to complain about. No they weren't transformational deals but we're clearly more than a couple pieces away. Unfortunately. It doesn't look like we're making it to the playoffs but we were close enough to take a swing at it when the deals were made.
