Panthers WR Steve Smith (5-9) has been the primary target in Carolina for most of his nine-year career, during which he's been to four Pro Bowls, including in 2005 when he was the NFL leader in receiving yards (1,563), receptions (103) and receiving touchdowns (12). (AP Photo/Chuck Burton)

David Patten (5-10) has been with five different teams in his 12-year career. His most notable tenure was with the Patriots from 2001-2004, when he was part of three Super Bowl titles. After being out of football in 2009, Patten is returning to New England next season. (AP Photo/Tony Tribble)

Wes Welker (5-9) has had more than 100 receptions in each of his three years with the New England Patriots, leading the league in 2007 (112) and 2009 (123). Welker suffered a tear in his ACL and MCL in Week 17 last year, and his return for the start of the 2010 season is uncertain. (AP Photo/Stephan Savoia)

Since leaving the Patriots in 2005, WR Deion Branch (5-9) hasn't quite caught on with the Seahawks. He's failed to play a full season in Seattle, and his best season was in 2006 when he finished with 53 catches for 725 yards and four touchdowns in 14 games. (AP Photo/Paul Spinelli)

Lance Moore (5-9) was a big part of the Saints' aerial attack with a breakout 2008 season in which he had 928 receiving yards and 10 touchdowns. But hamstring and ankle injuries allowed him to play in just seven games last season. (AP Photo/ Bill Nichols)

Antwaan Randle El's (5-10) best years were with the Pittsburgh Steelers as a return specialist and third wide receiver. He threw a touchdown pass in the Steelers' 2005 Super Bowl victory. Maybe that's why he's returning to Pittsburgh in 2010 after four seasons with the Redskins in which he never lived up to expectations. (David Drapkin/AP Photo)

Santana Moss (5-10) has been a decent No. 1 receiving option in his nine-year career, finishing with more than 1,000 yards three times, once with the Jets and twice with the Redskins. Moss made his only Pro Bowl appearance in 2006, his first year in Washington, when had 84 catches for 1,483 yards and nine touchdowns. (AP Photo/Greg Trott)

Eddie Royal (5-10) had a stellar rookie campaign as a No. 2 receiver in 2008, finishing with 91 receptions for 980 yards and five touchdowns. But he failed to follow that up last season, compiling just 37 catches for 345 yards and no TDs. The Broncos will definitely want him to return to his rookie ways in 2010. (AP Photo/Nick Wass)

In just two years in the NFL, DeSean Jackson (5-10) has proved himself as a dual big-play threat as a receiver and punt returner. He was voted to the Pro Bowl in 2009 for both positions after scoring eight touchdowns of over 50 yards, which tied an NFL single-season record. (AP Photo/Mel Evans)
