I see what the OP is trying to say, but I think a lot of people are overlooking the underlying theme of greed. Every smart GM in the league is trying to hoard assets, and flip them for more than their original value/acquisition. At this particular point in time, we had a few top 10-15 players who were all made "available" (a very abstract word in the trade market).
Everyone in the league also knows that outside of Philly maybe, the Celtics have the best package of easily liqubable and high-value trade commodities between their combination of picks/young prospects/amazing contracts.
Players like Jimmy Butler, Paul George, etc., on failing teams or mediocre ones, only lose trade value as their contracts get closer to expiration.
THIS is what many on this board are not understanding. Did Ainge p--- away the 2017 season? Hardly! We have the 5th best record in the league as we are "rebuilding". Why is Philly so far down in the standing having had a half decade of top 5 picks and cap space? Bottom line is that the GM's for the teams we were having discussions with got GREEDY. They thought we would cave or some other team would and send them a treasure trove of assets which BUYS THEM MORE TIME.
This is why Ainge is the best poker player in the league. He knows he's sitting with pocket aces. The river hasn't happened yet. The turn will be this years draft once the ping pong balls fall. Right now he was probably hearing, "oh, well this is the 4th pick at best...." When Brooklyn officially finishes in last, and we have a 70% chance of the pick being 1, 2, or 3, it changes everything! If it turns in to #1, we will be able to flip just this pick, maybe a mid level prospect like Rozier, and cap filler for Butler, and especially George, just like Cleveland did when they traded #1 for Kevin Love (which I'm sure they now also regret).
This is only going to get better, and we as Celtics fans, need to stand pat too. Stand back with a positive attitude, and watch a fun and competitive team do their thing! The rest will absolutely fall in to place.
