Honestly I know it's a mixed bag on the decision to trade JB I think the biggest issue where people felt Brad dropped the ball is on the return we got for JB.
I think this is absolutely correct. I know that I felt we would get a lot more for him than Paul George and a mix of first round and second round picks. The picks are looking better to me than they did at first, but still, I went from thinking we would get Giannis to having to "settle" for Paul George.
The other complaint that is potentially fair is the timing of trade. Could they have gotten more for him if they had traded him a year ago or at the deadline. The report was they asked GSW for (4) firsts, what MEM got for Desmond Bane, but GSW said pass. I don't know if Brown's value was higher if they had traded him earlier, no one knows. We all think he was worth more, but maybe not.
I am pretty sure he was not worth more, or if he was worth more it was only to teams that he then back channeled his way out of a trade. Last offseason he had a torn meniscus; if he was worth more then than after this year when he had an All-NBA season then there is something odd going on with trade values. I find it inconceivable that the Celtics talked to probably a dozen teams and did not have a good idea what JB was valued at. They clearly started with a much higher asking price and could not get close to it, and went with what they thought was best. And something was going on that we may never know that made the Celtics 100% committed to trading him no matter what. I do not think it was the dollars that made it urgent.
The unrebutted reporting is that Brad started each negotiation with an insanely high asking price, causing most teams to quickly move on to other options which were coming off of the table extremely quickly.
So, perhaps you can assume that Brad took the best deal that remained on the table, but I don't think that in any way we can assume that Brad traded JB for the max value a team would have paid this off-season.
Unrebutted reporting? No one is even putting their name out there. We have unnamed sources saying the Celtics went too high and scared teams off. We have other unnamed sources saying their team low-balled and the Celtics never called them back.
What we seem to know with the most confidence is the Celtics were asked for three firsts and two young players in addition to JB for Giannis. And the Heat traded 3 firsts, three young players, a swap, and a second along with Tyler Herro. They also got Portis. If we say Portis was worth a second, then we see the difference in value the Bucks ascribed between JB and Herro was a 1st-round swap and a prospect. Ignoring the impossibility of the salary matching, would you have been more or less angry if we traded JB for Tyler Herro, Kasparas Jakucionis, and a swap 4-6 years down the road? Because that was the implied value of JB. I think it is worse than what we got. If you want to say you would prefer that, I am not going to argue with you, but I do not think you can say it is vastly superior. It is at worst in the same ballpark.
