People who believe we traded value for Garnett and Allen are living in a deep world of denial.
Danny was there when two HOFers were being shopped for pennies on the dollar.
Our pennies landed the day.
In NBA history older HOF type players have been traded for similar packages. I'd say it's more the rule than the exception. Allen, who plays a position not kind to older players, was seen as in decline, coming off an ankle operation. Seattle got what were considered two solid rotation guys and a top 5 pick.
In the KG deal, Minny got one of the best young post players in the league. The rest of the package, in hindsight, was garbage, but at the time, Green, Telfair and Gomes were considered NBA rotation players. They got a 6th pick, and foolishly chose Jonny Flynn instead of Steph Curry. Ellington at 28 was a decent pick. If Minny took Curry, as they should have, and stuck with Big Al and Ellington, their haul for KG would look better. They got Kosta Koufos and two first for Al.
Looking at past trades of declining HOFers, teams either get back the classic "two dimes for a quarter" (Barkley for Hornacek and Perry), or a combination of lesser players and first round draft picks. It's what you do with those players and draft picks that will determine if the trade was worth it.
If Minny took Curry instead of Flynn, kept Koufos instead of trading him for Anthony Randolph and Eddy Curry, and did more with the draft picks they got for Big Al (they could have had Chandler Parsons, Jared Sullinger and Nicola Mirotic, who could be a Dirk like player, amd will be in the NBA in the summer of 2014), they'd look differently at the KG trade. Curry, Parsons, Sullinger and Mirotic for KG would look pretty good in a few years, added to the players they got with the high picks they "earned" when losing post-KG.
With the KG trade to the Clips, (a two dimes for a quarter trade) Boston already know what they're getting - two young guys with great potential. DJ is already a solid player at a position difficult to fill, and Bledsoe looks to be a breakout performer. That's a good haul for an aging HOFer with only a few seasons left in the tank.
