Tracking top wide receivers available for Ravens

The Baltimore Ravens are still in the market for a wide receiver after Torrey Smith signed with the San Francisco 49ers. The only returning wide receiver who caught more than 25 passes last season for the Ravens is Steve Smith, who turns 36 in May.

The pool of available receivers has dwindled as 20 have signed or reached agreements since the start of free agency on Tuesday. Let's take a look at the top 10 receivers who remain on the market, all of whom have watched their receptions decline in recent years:

1. Michael Crabtree, 49ers: Even though he's clearly the best receiver remaining, his value likely dipped after missing out on the first surge of free agency. Crabtree has dropped more passes than you would like to see from a possession receiver, but he's only 28 and quarterbacks had a 91.1 passer rating when throwing to him, according to Pro Football Focus. The biggest challenge for Crabtree is staying healthy. The Redskins and Chargers have expressed interest, according to ESPN Redskins reporter John Keim.

2. Dwayne Bowe, Chiefs: The 30-year-old receiver is a big, physical receiver who isn't afraid to go over the middle. Bowe has some off-the-field issues and didn't score a touchdown last season. His first visit was with the Cleveland Browns and it went very well, according to ESPN's Adam Caplan.

3. Stevie Johnson, 49ers: He's only 28 with size (6 feet 2) and a reputation as a good route runner. Johnson was virtually nonexistent last season, catching 35 passes for 435 yards (his lowest output since his second year in the league). He is visiting New England on Monday after meeting with the San Diego Chargers. Update: Johnson signed with the Chargers.

4. Greg Jennings, Vikings: Released by Minnesota on Saturday, Jennings put up average numbers in two seasons with the Vikings while catching passes from four different quarterbacks. He's still a savvy receiver who can be effective out of the slot. At the age of 31, he's just not a No. 1 receiver or a big threat on the outside.

5. Cecil Shorts, Jaguars: He produced some nice moments early in his career, but nagging injuries and the lack of big plays (no touchdowns after Week 1) make him a low-end No. 2 receiver. Shorts is visiting the Texans on Monday, according to the Houston Chronicle's John McClain. He has drawn interest from the Chargers, Jets, Browns and Dolphins. Update: Shorts signed with the Texans.

6. Denarius Moore, Raiders: He has great speed and has the potential to be a serious deep threat. In 2012 and 2013, Moore caught a total of 97 passes and averaged 14.8 yards per catch. But he played only 10 games last season and made 12 receptions. Moore would replace the speed void left by Torrey Smith.

7. Hakeem Nicks, Colts: The dropoff continued for Nicks, who managed 38 catches in 2014 (the lowest of his six-year career). There's always a lingering feeling that he could turn his career around because he's only 27.

8. Mike Williams, Bills: He has only 30 catches the last two seasons, and he comes with a lot of baggage. But Williams is 27 and a big target in the red zone.

9. Nate Washington, Titans: He's had a modest nine-year NFL career, but he makes the most of his catches. Washington has averaged 16 yards per reception over the last three seasons.

10. Miles Austin, Browns: He's a dependable 30-year-old possession receiver. Austin produced nearly 200 yards on third downs in 12 games before being placed on injured reserve.

Others: Reggie Wayne, Jarrett Boykin, Vincent Brown, Derek Hagan, Jerrel Jernigan, Donnie Avery, Lance Moore and Robert Meachem.
