4. Brandon McManus, Jacksonville Jaguara
When the Broncos cut McManus, he was an instant possible fit for the Lions to supplant the re-signed Badgley. He landed quickly with the Jaguars, and given how it's worked out for Denver's kicking situation it was probably a mistake by them to let him go.,
The Jaguars are one of few teams with two kickers on their roster right now, late Tuesday morning as of this writing (the Lions among them of course). It's easy to just ink McManus as the guy for them, but if multiple teams are calling around about kickers it makes some sense he's a target and the Jaguars have fielded calls.
The Jaguars are probably hanging up the phone if someone wants to try to make a deal for McManus. But if they're not, there's a non-zero chance he'll be traded and the Lions should be among the teams with interest.
3. Nick Folk, New England Patriots
Folk is lined up to lose the Patriots' kicking gig to fourth-round rookie Chad Ryland. His overall field goal rate "dropped" to 86.5 percent last year, after topping 92 percent in each of the previous two full seasons in New England. But at 38 years old (39 in November) he still has plenty of range and Bill Belichick trusted him to make kicks from long range, with 11, 11 and 10 attempts from 50-plus yards out the last three seasons.
Folk could easily be added to the list of available free agent kickers. But the Lions almost certainly have made a call with trade interest, as he's clearly not long for the Patriots' roster.

Update: Folk has reportedly been traded to the Tennessee Titans.
