New Orleans Saints at the Pittsburgh Steelers pregame chat with Advocate sportswriter Nick Underhill, Sunday at 11 a.m. _lowres

Advocate staff photo by ELIOT KAMENITZ--Former Saints tight end Jimmy Graham scoeres a touchdown in the first quarter as Ravens strong safety Will Hill defends last season.

Jimmy Graham was as shocked as everyone else when he learned that he was being traded to the Seattle Seahawks.

“I was actually on a beach down in Florida when I got the call from Sean Payton letting me know that I had just been traded,” Graham said during a conference call with Seattle media. “I was just working out and kind of doing my offseason thing, and next think I know I’m a Seahawk.”

Graham was traded to Seattle earlier this week along with a fourth-round draft pick in exchange for center Max Unger and a first-round pick.

He said that he spoke with Saints General Manager Mickey Loomis last month and was discussing the 2015. He had no indication that he might be moved and said the trade was “definitely out of left field.”

“So for me it was a moment of shock, but once that shock cleared, I realized that I was going to the best team in football,” Graham said.

Seattle quarterback Russell Wilson has said he models his game after Graham’s former quarterback, Drew Brees, but the tight end said he views them as being different players.

“Russell really will run with the ball,” Graham said. “Drew will really, really stand in the pocket no matter what. He rarely, rarely runs it.

“So I was watching a lot of film where Russell will ends up kind of breaking out of the pocket, and really that’s when he’s scary and when coverages are broken down and you have to respect him as a runner because he’s so good at it, and he’s able to get these shots down the field and these huge, game-changing plays, so I’m really looking forward to really seeing that for the first time because Drew really is a pocket passer.”

Spiller visits

The Saints have at least some degree of interest in further solidifying their running game.

Less than a week after re-signing running back Mark Ingram to a four-year, $16 million contract, New Orleans is now showing interest in former Bills running back C.J. Spiller and will meet with him Thursday, according to a source.

Spiller would likely be plugged into the role created by the release of Pierre Thomas if signed by the Saints.

The 27-year-old was limited to nine games last season, rushing for 300 yards and catching 19 passes for another 125. His best year came in 2012 when he rushed for 1,244 yards and caught 43 passes for 459 yards.

Spiller was still at the team’s facility late Thursday evening.

Williams leaves

Tramon Williams’ visit with the Saints ended without a deal.

The cornerback and former Assumption High standout visited with the Saints Wednesday but left town Thursday without a signed contract and will now mull over his options, according to ESPN.

It’s not known if New Orleans would have interest in signing the cornerback with Brandon Browner now in the fold.

A former member of the Green Bay Packers, Williams, 31, intercepted three passes last season and recorded 71 tackles. His best season came in 2010 when he picked off six passes.

Humber returns

The Saints re-signed linebacker Ramon Humber to a two-year deal, the team announced.

New Orleans expressed interest in retaining Humber earlier this week.

Humber appeared in 15 games last season, logging 453 snaps on defense playing predominately at weakside and strongside linebacker. Humber also played middle linebacker, so his return is important given the departure of Curtis Lofton.

Humber also serves on special teams.

Walker Walks

The Saints left Tyrunn Walker unprotected and he got away.

The defensive tackle has signed a one-year deal with the Lions worth $1.75 million with a $750,000 signing bonus, agent Sean Kiernan told multiple media outlets.

The Saints could have tendered Walker, who was a restricted free agent, which would have required an initial one-year, $1.54 million offer. The team would have then obtained the right of first refusal on any offers from another team.

An undrafted free agent in 2012, Walker provided depth at both tackle and defensive end and showed promise on the defensive line last season by recording 2.5 sacks and forcing a fumble.
