They're the hottest team in the NBA, with a record (19-2) that exceeds rational forecast or reasonable expectation.

And while the Warriors have spent a disproportionate amount of time away from Oracle Arena, the travel demands have been cushioned by a schedule featuring a succession of inferior teams.

We take this into account as the Warriors conclude the first quarter of the 2014-15 season under rookie coach Steve Kerr.

Here is the report card for those coming off the bench:

Leandro Barbosa: C

Hired to help with the team's transition to a new system -- one he grew familiar with in Phoenix -- Barbosa has been inconsistent in every way. The veteran looks OK one minute, and then seems unable to help at all. His spot in the rotation is in jeopardy.

Festus Ezeli: C+

We're taking into account the limited minutes the backup center has gotten, and the fact that he missed all of last season. He clearly has worked to develop his game, and has done enough to merit more playing time.

Justin Holiday: I

After making the club by being solid at both ends during the preseason, Holiday has played a total of 47 minutes in the 21-game first quarter. That could change if Barbosa doesn’t get his act together.

Andre Iguodala: B-

His shot has been absent more often than present, yet the veteran wing seems to invent ways to contribute. He generally defends at a high level, and he's a very capable playmaker. He has handled his new role, off the bench, like a professional.

Ognjen Kuzmic: I

Kuzmic continues to work on his game but has been confined to blowout patrol, playing only a team-low 32 minutes in the first quarter.

David Lee: I

After missing the first three games, the veteran power forward returned for Game No. 4, coming off the bench for seven minutes before aggravating his strained left hamstring. He has yet to return.

Shaun Livingston: B

As a result of offseason foot surgery, the veteran point guard spent half the first quarter a step behind. His recent terrific play at both ends is pushing him into B+ territory, though.

Brandon Rush: C

The veteran wing is nowhere near the guy who might have been the team's best two-way player in 2011-12. It's evident that his confidence is shaken. A 41-percent 3-point shooter, he's shooting 9.1 percent beyond the arc this year.

Marreese Speights: A-

Scoring like a machine, rebounding better than ever and blowing considerably fewer defensive assignments, the veteran big man has played his way into the center of the Sixth Man of the Year chatter.
