Throughout the career of the arguably best point guard of all time Steph Curry he has has Klay Thompson for a while but adding KD made it too easy winning 2 of 3 championships in the years of KD being a warrior.
The history behind KD leaving OKC to form a super team with the warriors mainly because to win a championship, nowadays to even contend for a championship you will need better than average players around them you would need to have 5 stud players that take in 10 million or more a year to contend and make the playoffs at the bare minimum.
The situation with KD leaving OKC was out of pure disrespect, telling Westbrook he was not leaving then Westbrook later told by (the press how do you feel about KD signing with Golden state?
After Durant left OKC everything went down hill for the Thunder with Westbrook leaving to join Harden the ball hog and Kevin Durant yet leaving the Warriors and joining Kyrie in Brooklyn. Considering now that Kevin Durant is out for the season due to his achilles and Kyrie cant stay healthy they would be best off tanking to get another shooter to go along with Kyrie Joe Harris, Jared Allen and Durant.
OKC has went to junk their point guard and there franchise now relies on a terrible and 65 year old Chris Paul that can't make it up the court without passing out. For the Nets now they have been carried by the fro Jared Allen and the best point guard in the league Kyrie Irving, no one can guard Kyrie 1v1 and that is what the nba has come too.
The warriors now have Draymond as there only All star healthy at the moment with Klay out and curry there season is going to be atrocious with be lucky to win 40 games with how bad there team is.
