Suns' Coach Mike D'Antoni cannot figure out why Boris Diaw is struggling to team with healthy All-NBA big man Amare Stoudemire.

"They should be really good together," D'Antoni said. "Boris facilitates the ball, and Amar? is one of the best finishers in the business. It's a little bit of a mystery."

D'Antoni remains confident that Diaw will figure it out.

"There's really no good reason for it," he said, adding that most of whatever problems the Suns have had are related to effort and focus throughout the lineup.

"That's kind of the story of our team right now," he said. "It just comes down to heart and soul - play hard, and let's go."
