Our free-agent tracker lists 32 potential starters left on the market. The teams below should be hot on the trail of those players to round out the weak spots on their rosters.
Here are positions that still need to be filled in free agency:
1. Cowboys defensive line: Unable to afford DeMarcus Ware and Jason Hatcher, the Cowboys have a fair claim to the league's shallowest defensive front. Signing Henry Melton would help, but it's still a downgrade in talent and productivity.
2. Panthers wide receiver: On the same day that Steve Smith signed with the Ravens, the Panthers landed a blocking tight end with five career receptions -- three more than all wide receivers on the roster combined. After missing out on hometown hero Hakeem Nicks, there's pressure to land a starting-caliber receiver.
3. Raiders: General manager Reggie McKenzie is still armed with the most salary-cap space in the league after adding four starters on defense and a right tackle. Now he's tasked with finding a quarterback, left tackle, guard, run-plugging defensive tackle and safety.
4. Jets cornerback: The pressure is on the Jets to land a top-tier corner after dumping Antonio Cromartie, missing out on his cousin Dominique Rodgers-Cromartie and whiffing on a potential reunion with Darrelle Revis.
5. Redskins safety: The early run on top-tier safeties has left the Redskins with Brandon Meriweather and unproven Phillip Thomas penciled in as the starters. They remain in the market for a veteran, such as Ryan Clark.
7. Colts center: Phil Costa was signed for depth, but the interior of this offensive line is still a need area. General manager Ryan Grigson picked up Hakeem Nicks for a song, leaving enough room in the budget for a run at Browns transition player Alex Mack.
8. Titans pass rusher: In the market for edge rushers to smooth the transition to his 3-4 defense, new coordinator Ray Horton had his eye on LaMarr Woodley only to see him take the cash grab in Oakland.
9. Giants tight end: New coordinator Bob McAdoo has made it clear that tight ends will play a big role in his offense, but Andrew Quarless re-signed with the Packers, Brandon Pettigrew returned to Detroit and Jermichael Finley likely is headed to Seattle. The pickings are now slim, with Owen Daniels as the best available.
