Three weeks into the season, Warriors point guard Jarrett Jack was frustrated. He felt he wasn't playing enough or doing enough.

But his ire wasn't directed at coach Mark Jackson. In a heart-to-heart with starting point guard Stephen Curry, Jack singled out his own poor play for keeping him on the bench.

"That's when I knew he was for real," Curry said. "I knew it wasn't just smoke he was talking in practice. He was a true leader that was trying to help change the culture."

Since then, Jack has been so much more than just a reserve guard for the Warriors. He's been a floor general, a scorer, a leader, a motivator, a closer. He's been a bargain for the $5 million salary he's earning, especially considering the minimal cost it took to acquire him -- small forward Dorell Wright as part of a three-team trade.

In seven games this month, Jack is averaging 20.1 points and 6.9 assists. That's coming off a January where he averaged 13.7 points and 7.3 assists.

And if the Warriors win at Indiana on Tuesday, Jack -- a former Pacer -- will probably have a major hand in it.

Part of the reason Jack's presence has been so beneficial is his willingness to embrace his role. Unlike in past years, when tension -- real or perceived -- existed between Curry and Monta Ellis, Curry and Jack seem to be in sync.
