As news broke that DeMarcus Cousins has agreed to join the back-to-back defending champs Golden State Warriors, several NBA players quickly reacted to the big news. Among those included Bobby Portis of the Chicago Bulls who gave us a little lesson from the past.

Via his Twitter account, Portis said:

Cousins agreed to a one year, $5.3 million deal with the defending champions. He'll be joining the powerhouse lineup comprised of Stephen Curry, Klay Thompson, Kevin Durant, and Draymond Green.

Back in 2011, the Los Angeles Lakers tried to assemble a team — not the same powerhouse as that of the present-day Warriors — but a team comprised of Kobe Bryant and Chris Paul.

The New Orleans Hornets — Paul's team at that time — agreed to a three-team deal which would send him to the Lakers. But in a controversial move, David Stern — NBA Commissioner during that time, vetoed the deal. Paul still did go to Los Angeles, but with the Clippers. The decision gave rise to several controversies involving Stern and the whole NBA.

Via a statement, Stern reasoned out that New Orleans would be better off with Paul, per CBS News:

Since the NBA purchased the New Orleans Hornets, final responsibility for significant management decisions lies with the Commissioner's office in consultation with team chairman Jac Sperling. All decisions are made on the basis of what is in the best interests of the Hornets

In the case of the trade proposal that was made to the Hornets for Chris Paul, we decided, free from the influence of other NBA owners, that the team was better served with Chris in a Hornets uniform than by the outcome of the terms of that trade.
