ATLANTA -- Less than three weeks before the start of training camp, the Atlanta Falcons know Michael Vick tops their quarterback depth chart, but the team isn't quite so certain yet to whom he will be throwing in his first season as an NFL starter.

That was further evidenced Tuesday when the Falcons visited with veteran wideout Willie Jackson, one of the top players still remaining in the unrestricted free agent market.

Jackson, 30, is coming off a superb season in 2001, one in which the eight-year veteran caught 81 passes for 1,046 yards -- both career-highs -- and five touchdowns for the New Orleans Saints.

A former University of Florida standout, Jackson is one of the few players still garnering plenty of offers in the waning days of free agency and Atlanta is just the latest franchise to bring him in for a visit. About three weeks ago, Jackson rejected a two-year proposal from the San Francisco 49ers, with the deal worth about $2.5 million. His rationale was that he might only be the No. 3 wide receiver there behind Terrell Owens and J.J. Stokes.

He has also drawn interest from Washington and Tampa Bay.

"There's a really good market for him right now," agent Joel Segal said. "I'm certain he could help them (in Atlanta), but we'll have to see how it plays out."

To this point, the Falcons have eschewed all of the high-profile wide receivers in the free agent market, preferring instead to develop some of their own younger players. But there is some feeling that Vick could still use a steady and fleet veteran and the Falcons brass might suspect that Jackson has lowered his contract expectations as camp grows nearer.

ESPN.com has learned the Falcons spoke last week with veteran wide receiver Yancey Thigpen, who did not play in the league in 2001, but that he declined a workout request because he was getting married. Atlanta may revisit its interest in Thigpen, a former Pro Bowl-caliber receiver, but not until camp begins.

For now, the projected starters are Shawn Jefferson and Brian Finneran, but the former is nearing the end of his career and the latter is relatively inexperienced. The Falcons added 11-year veteran Jeff Graham in free agency but he has missed much of the spring work because of potential legal problems.

Atlanta released a pair of veteran wideouts, Tony Martin and Terance Mathis, in recent months and the club is hoping younger players like Finneran, Shawn Mills and Quentin McCord can fill the void. Former Jacksonville Jaguars backup Alvis Whitted has shown great speed in minicamps but has always been an inconsistent receiver.

Jackson would provide Vick, who started only two games as a rookie in 2001, with a proven playmaker. While he might lack the pure deep speed of some younger players on the roster, Jackson still has the ability to separate from a cornerback and he will usually make the tough catch in traffic as well.
