Anquan Boldin said he and Larry Fitzgerald remain close and still keep in touch after six seasons together in Arizona when they were the league's most fearsome receiving duo.

You have to wonder if the theme of their recent messages has been: Wish you were here.

Both enter today's game at Candlestick Park as part of paltry passing attacks.

Fitzgerald's Cardinals are 22nd in passing offense and his quarterback Carson Palmer has thrown nine interceptions tied for second most with Houston's Matt Schaub.

The 49ers' passing offense is 31st averaging just 182 yards partly because in the past two weeks the running game has awoken and the defense has held opponents to just 14 points.

The 49ers simply haven't needed to put the ball in the air. And aside from Boldin quarterback Colin Kaepernick hasn't had a lot of options when he does drop back to pass.

Boldin said this week he is seeing more double teams than at any other point in his 11-year career.

Offensive coordinator Greg Roman agreed.

"He got doubled quite a bit last week especially on third down" Roman said. "There's a lot of different ways you can play doubles and he's seen all of them this year. And it's just becoming more prevalent. And it's to be expected really."

Through five games Boldin has 67 percent of the team's wide-receiver catches 78 percent of the wide-receiver receiving yards and all of the team's wide-receiver touchdowns.
