Celtics added Allen and Garnett after they had played 12 seasons and their teams were going into rebuilds. Danny Ainge pulled off the trades and it wasn't players demanding trades to a certain team. Boston, Minny, and Seattle were at the bottom of the standings. Did they buy a championship, yes, was it like what Lebron did in Miami, no. Cleveland was a Playoff team, Miami was a playoff team and Toronto missed the playoffs by 1 win on the last day. Lebron, Wade, and Bosh all were in the beginning of their primes. What Boston did was like what the Houston rockets did when they added Pippen and Barkley or when the Lakers added Malone and Payton. Bring older vets(still good) in to win.
Lue wasn't hired as a coach because he is not a good coach. LA didn't want him. There were not many coaches to chose from especially proven ones. Last season the Lakers knew it was a wasted year. They wanted to just make the playoffs.
The heat had a solid team without Lebron and Bosh. Riley wanted championships. Bosh, wade and Lebron had it planned for years that they were going to play together.
The Warriors are every bit how you build a championship roster. Green, Thompson, and Curry where all drafted by GS. The Warriors aren’t an accident or an evil conglomerate that was built unfairly. They were the smartest with their patient use of the draft. When Lebron started saying in the media we need to add another player to compete he was refering too Carmelo Anthony. All the media outlets where saying it. It was like Lebron was trying to use public pressure to get Gilbert to do it. GS turned around and added KD. That move was in response to Lebron + because of Golden States management of the salary cap, they had more than enough room to fit KD in. Cleveland were trying to buy itself to victory.
