What besides, Golden State loosing Draymond Green for game 5, has changed with the Cavs?
What has Lebron asked of them, that has changed them enough to possibly win the NBA championship. Because I'll tell ya, after game 4 that team look beaten, so what changed?
The thing I noticed was a total commitment good hard defense. Tristan Thompson and LBJ are really controlling the offensive, and defensive boards. I fact... you go into the paint at your own risk. Picks are now fought over, passing lanes are being over played. The defense has really tightened up starting in game 5. Players that simply don't defend well, are at least playing hard, and physical, and working at it. Irving has forced Curry to have to defend him, and he's not liking it. While at the other end, Cleveland guards, including even Irving, are playing tough, honest, physical D. The entire Cavs team is making it hard on Curry and Klay. (like the C's did in ending the Golden State home winning streak)
The Warriors with all that scoring and 3 point shooting, are having trouble with aggressive, tough Defense. I know many think todays NBA is all about shooting and scoring, and to a certain degree you're right, you need a few players that can score well.
But aggressive tough D can be darn effective, especially in the playoffs. The problem is, if your a poor defender, you can't just turn it on, nothing to turn on, if it's simply not there.
A team also needs talented tough minded defenders.
