Walker's Fab 40: Nos. 21-24

ESPN.com’s Miami Dolphins page continues to rank the top 40 players on the team.

Next up, we take a look at Nos. 21-24.

No. 24: Dustin Keller

Position: Tight end

2013 stats: No stats

Analysis: The Dolphins had high hopes for Keller, who signed a one-year contract last season. Keller was having a solid training camp and preseason before suffering a terrible knee injury in a preseason game against the Houston Texans. Keller is rehabbing multiple knee ligaments and needs to prove he’s 100 percent again before another team signs him. A return to Miami appears unlikely. Charles Clay stepped in for Keller and had a terrific year with 69 receptions.

No. 23: Chris Clemons

Position: Safety

2013 stats: 92 tackles, one interception

Analysis: Clemons had another productive year in Miami. He was fourth on the team in tackles and showed toughness by working through multiple injuries in the second half of the season. Clemons’ coverage is inconsistent at times, but he’s a sure tackler. Clemons is an unrestricted free agent. The Dolphins must decide if they want to spend to bring Clemons back or if they can get an upgrade elsewhere.

No. 22: Koa Misi

Position: Linebacker

2013 stats: 54 tackles, two sacks

Analysis: Misi was part of an underachieving linebacker corp. But Misi was active and had six tackles for losses. The Dolphins would like to see more big plays from Misi in terms of sacks and interceptions. He received a contract extension from former general manager Jeff Ireland during the season.

No. 21: Brandon Gibson

Position: Wide receiver

2013 stats: 30 receptions, 326 yards, three touchdowns

Analysis: Gibson was catching his stride in the slot before suffering a season-ending knee injury. Getting back to 100 percent will be key for Gibson in an already deep receiving corp. Gibson is slick route-runner who is good at finding openings. He’s also a smart player with good hands.
