There's a little less than a month before the NFL draft and as the Detroit Lions proved late last week, there are still free-agency signings to be made and moves to be had.

The roster looks a little fuller than the last time we took a peek at what Detroit has -- and there is still a lot more filling out to do, particularly on the offensive and defensive lines. But as we head into the stretch run before the draft with the Lions due to report to Allen Park, Michigan, two weeks from Monday, here's a look at where Detroit's roster stands as of now.

Quarterback: Starter -- Matthew Stafford. Reserves -- Dan Orlovsky, Kellen Moore.

Thoughts: This position group is likely set, although a fourth quarterback could be added for camp purposes.

Running back: Starter -- Joique Bell. Reserves -- Theo Riddick, George Winn, Emil Igwenagu (FB).

Thoughts: There will be an addition here, perhaps two if the Lions want a true fullback competition. Figure a draft pick gets used at this position.

Wide receiver: Starters -- Calvin Johnson, Golden Tate. Reserves -- Jeremy Ross, TJ Jones, Corey Fuller, Ryan Broyles, Skye Dawson, Andrew Peacock.

Thoughts: Like running back, this is a position where a draft pick will almost certainly come into play. The Lions need a returner to push or replace Ross and need to eventually draft a successor to Johnson.

Tight end: Starter -- Eric Ebron. Reserves -- Brandon Pettigrew, Joseph Fauria, Jordan Thompson.

Thoughts: The Lions need Ebron to start, although Pettigrew will remain on the field a lot. This group is likely set.

Offensive tackle: Starters -- Riley Reiff (LT), LaAdrian Waddle (RT). Reserves -- Cornelius Lucas, Michael Williams.

Thoughts: Reiff isn't locked in at left tackle but is as a starter. Waddle's health will be something to watch and if the team spends a high pick here, it could push one of the two out of the starting lineup.

Interior line: Starters -- Rodney Austin (LG), Travis Swanson (C), Larry Warford (RG). Reserves -- Taylor Boggs, Darren Keyton, Braxston Cave.

Thoughts: This is where the Lions have the most work to do. Austin is a placeholder starter on the roster right now and will likely be fighting for a roster spot once camp starts. Don't be surprised if Detroit adds two players here who end up on the 53-man roster in a veteran unsigned player and a groomed rookie. Boggs could be intriguing, though.

Defensive end: Starters -- Ezekiel Ansah, Jason Jones. Reserves -- George Johnson, Darryl Tapp, Devin Taylor, Larry Webster, Phillip Hunt, Kerry Hyder, Roy Philon.

Thoughts: The Lions are pretty set here, although if another team signs Johnson it would create a hole to be filled either by Tapp, Taylor, Webster, Hunt or a free agent. Johnson's status is one of the bigger questions between now and the draft.

Defensive tackle: Starters -- Haloti Ngata, Tyrunn Walker. Reserves -- Jermelle Cudjo, Caraun Reid, Xavier Proctor.

Thoughts: A draft pick is coming to this position group. The only question is whether it is a first-day or second-day pick. Ngata and Walker are locks for the team. Everyone else is a question.

Linebacker: Starters -- DeAndre Levy, Stephen Tulloch, Kyle Van Noy. Reserves -- Tahir Whitehead, Josh Bynes, Travis Lewis, Brandon Copeland, Julian Stanford, Jerrell Harris.

Thoughts: This is, for now, the deepest position group on the roster. Can't see much more being added here other than an undrafted free agent or two.

Cornerback: Starters -- Rashean Mathis, Darius Slay. Reserves -- Bill Bentley, Nevin Lawson, Josh Wilson, Crezdon Butler, Mohammed Seisay.

Thoughts: A draft pick likely comes here as well, although Detroit has bigger immediate needs. The signing of Wilson gives depth to the nickel spot and should put some pressure on Bentley to contribute in a contract year.

Safety: Starters -- Glover Quin, James Ihedigbo. Reserves -- Isa Abdul-Quddus, Don Carey, Nate Ness.

Thoughts: Like last year, figure an undrafted free agent or late-round pick might slide in as well, but the top of this position group is set.

Specialists: Matt Prater (K), Sam Martin (P), Don Muhlbach (LS).

Thoughts: The Lions will probably bring in camp legs at kicker and punter. Thompson, a tight end, is the likely backup long-snapper.
