Warrior-Clipper games are going to be intense for the next several years to come. It's going to be great. You really can't feel like the Dubs didn't leave it all out there. A few bounces here and there goes the other way, the Warriors would be moving on, but that's how sports goes when two great teams go at it.
No coaching change is needed; Jackson just needs the right assistants for his personality, etc. He has a proven track record, and the fact he has players that buy into what he says, I don't know how you can fire him. Steve Kerr? No one has a clue how he'll be as a coach, at best, it's a lateral move, and at worst, a complete downgrade. If you go through the list of coaches you'd rather have besides Mark Jackson, there aren't a lot of names that can pop up in my head. I think he maximized, for the most part, what he could get from the team, and you can't blame him for the Bogut injury (I have no doubt if he was healthy the W's would be advancing)
Roster-wise, I think they just need to get healthy, and see what they can get for David Lee and/or Harrison Barnes.
