OAKLAND -- Warriors power forward David Lee, an All-Star 21 months ago, has played a total of seven minutes this season.
Point guard Shaun Livingston, who came to the team in July as a well-paid free agent, is playing limited minutes and concedes his conditioning is awful.
Center Festus Ezeli, who missed all of last season and most of training camp, also is restricted to limited minutes.
Stephen Curry, the All-Star point guard, owns career lows in shooting percentages -- overall and from 3-point range.
Veteran forward Andre Iguodala, uneasily adjusting to his new role as the leader of the second unit, has a player efficiency rating of 8.3 -- well below his standard and lower than those of Robert Sacre or Shelvin Mack or even the consistently inefficient J.R. Smith.
With so much that could weigh them down, how is it that the unbeaten (4-0) Warriors are soaring higher than we've seen in 20 years?
It's called depth, and they've never had so much.
"We have the deepest team in the NBA," coach Steve Kerr says. "Our roster is remarkable, not only the depth of talent but the versatility of that talent."
Third-string center Ognjen Kuzmic is the squad’s only one-position player. Everyone else is capable of playing at least two positions, and some, like Iguodala, can play three. Centers Andrew Bogut and Ezeli could play together, and will at times. There is an endless array of wings: Harrison Barnes, Brandon Rush, Justin Holiday, Draymond Green (in a pinch), Iguodala and Livingston.
Curry insists that this is the most complete roster during his six seasons with the Warriors.
"For sure," he says. "From top to bottom, for sure. We've got guys who started on teams before. We've got guys that have played significant roles on winning teams. And now they're all forming a great second unit.
"Realistically, we can go 11 or 12 deep and not miss a beat."
Kerr has turned to all 14 players on one night or another. Ten average more than 10 minutes per game, with Klay Thompson's average of 34 per game as team-high.
The Warriors have, for the first time since their championship era, a complete second unit ... and then some.
If Curry isn't bringing it, Thompson will. If Thompson isn't bringing it, Green will. Leandro Barbosa has been explosive off the bench. Rush is still rounding into shape. If none of those bring it, well, it was only nine days ago that Marreese Speights came off the bench to score 16 points in 18 minutes to spark the opening-night win over the Kings in Sacramento.
"You've got guys on the second unit, obviously, that have started a bunch of games in this league and can continue to start in this league," Green says. "For instance (on Wednesday) you had guy like Mo, who didn't play. He won us a game last week."
Kuzmic and Speights are the only players who didn't play in the blowout win over the Clippers. There will be more nights, however, with one or both will be needed. With Lee sidelined again, perhaps for an extended period, there can't be too many bodies.

"Just having that depth means a lot," Green says. "As this season goes on, you'll see it more and more. You'll probably see it more this weekend, with it being a back-to-back. That's the beauty of having the depth that we have."
The Warriors leave Oakland on Friday, headed for Houston to face the unbeaten Rockets on Saturday night. They'll leave Houston immediately afterward, bound for Phoenix, where they meet the Suns on Sunday.
They have three more occasions on which they'll play in different cities on back-to-back nights. They are, for now, well equipped for such a grind.
