They're really not. People don't realize it yet but the Warriors are an all-time great team along the line of the three Peat Bulls, Showtime Lakers, Big 3 Heat, Threepeat Lakers, etc.
You got 5 guys, in the starting unit, who can initiate a multitude of offensive sets and can take advantage of any weakness in a lineup. They got multiple great defenders and playmakers at almost every position, plus off the bench (Iggy and Livingston are matchup nightmares), and it's fueled by a 6'4 guard who can't really stopped by current defensive schemes.
I don't think people understand exactly how good Curry is at threes and what it means but Curry turns close games into blowouts in like 5 possessions.
And, IMHO, I think Golden State structured their team right. I'm of the belief that a championship team shouldn't have its most important offensive piece shouldn't be the defensive anchor too. The speed of the game is too fast and too physically demanding. It's why you see Butler's and George's and even CP3's struggling in the playoffs.
Draymond's emergence came at the perfect time.
Thing is everyone ain't Lebron, Kobe or MJ. Most great offensive players aren't great defenders. Curry is the weakest link defensively on the starting Five. But so was Magic, Bird and Dirk for example.
The key for the warriors to keep winning they must always have great SF and SG defensively to hide Curry. It is harder to hide wing players now due to the rule changes. Ideally it would be better to hide a PF or Center because of zone and the no hand check rule (which stops refs calling fouls when player post up unless they are in the triple threat).
