We can also praise coach Nash for doing a beautiful job so far. I guess being a player himself, he can relate to all of this high caliber players and bring team to a common goal, which is to win the NBA championship this year.
It is still a long way to go, yes they will be the favourite now, but for sure other teams will want to beat team and prove that they are not invincible even with that celebrated line up of 3 superstar + a lot of good caliber players.
Steve Kerr and Nash probably are the most luckiest coaches that ever existed. Steve Kerr took over a team that has curry, klay and draymond (with at the time bogut and iggy and livingston as well) and he had great run with it and added KD eventually to a team that broke the win record as well. Now nash took a team with Irving, Harden, Durant, Blake, Deandre, LMA and Joe harris as well, that is a great team to start your career.
I am not saying they are bad coaches by the way, I think they are good coaches but the fact is that they could have been in place of Silas as well, that dude is playing with Rockets and that team sucks right now, they even had a 20 loss streak, and it's his first head coaching job, he will have a very hard time with future head coaching job potentials. So even if you are good or bad, having a good or bad team matters a lot.
