On Day 1 of free agency, the Detroit Lions addressed arguably their four biggest needs.

They signed Danny Amendola to a one-year deal as a stopgap solution at the slot receiver spot, and agreed to long-term contracts with Trey Flowers, Justin Coleman and Jesse James to fill holes at defensive end, cornerback and tight end, respectively.

They're not done shopping yet, either. The Lions are still looking for a backup running back, help on the offensive line and in the secondary.

As Day 2 of free agency kicks off, here are 12 players to keep an eye on who could help the Lions in 2019 and beyond.

Running back

Mark Ingram, New Orleans Saints: It has been a slow-moving running back market so far. Le'Veon Bell, arguably the top free agent regardless of position, remains a free agent, and while his price point is entirely different from everyone else on this list, he might need to find a home before some of these other backs slot in. Ingram went to high school in Flint and worked as a part of a backfield tandem in New Orleans, so splitting time with Kerryon Johnson in Detroit shouldn't be an issue if the money matches.

Zach Zenner, Detroit Lions: Zenner is the only current Lion on this list, and there's still a chance he returns to Detroit. He played well when given the opportunity late last season and he adds value on special teams. He also won't cost as much as Ingram or Tevin Coleman.

Latavius Murray, Minnesota Vikings: Murray just turned 29 years old, and no one wants to spend on old running backs. But he's had just 899 carries in is NFL career and has split time the last two years with Dalvin Cook in Minnesota. He won't cost a ton and would provide good value as veteran insurance behind Johnson.

Jeremy Hill, New England Patriots: Another ex-Patriot, so of course he fits. But more than that, Hill played for new Lions running backs coach Kyle Caskey in Cincinnati. Hill missed most of last season with a torn ACL, but he's just 26 years old and was a 200-carry-a-year back early in his career with the Bengals.

Offensive line

J.R. Sweezy, Seattle Seahawks: The Lions cut T.J. Lang last week, opening up the starting job at right guard. They have in-house options in Kenny Wiggins and Joe Dahl, but Bob Quinn has never been one to neglect his offensive line. Sweezy can play both guard spots and has familiarity with new offensive coordinator Darrell Bevell from their time together in Seattle.

D.J. Fluker, Seattle Seahawks: Fluker has bounced around to three different teams the last three years, but he found a home last season as Seattle's starting right guard. He's a mauler who'd immediately upgrade the Lions' run blocking, but he's also coming off a severe hamstring injury that teams might want to get a physical on before agreeing to a contract.

Jeff Allen, Kansas City Chiefs: Wiggins started 10 games at right guard last season, so maybe the Lions are more comfortable than we realize with him as a starter. If so, a player like Allen would make sense. He can play every position but center and he won't cost a ton.

Bryan Witzmann, Chicago Bears: Witzmann is a massive human at 6 feet 7 and 320 pounds, and the Lions like their linemen big. He wouldn't be handed a starting job in Detroit, but he played well late in the season for Chicago last year when he filled in at right guard.

Defensive back

Eric Rowe, New England Patriots: The Lions spent big on Coleman, but with little proven depth behind him and Darius Slay, cornerback is arguably still their biggest position of need. Rowe is a risk because of his extensive injury history, but he has the size the Lions covet and was a part-time starter in New England when healthy.

The Associated Press

Marcus Gilchrist, Oakland Raiders: The Lions have options at safety. Tracy Walker is expected to replace Glover Quin in the starting lineup, but having another experienced hand at the position is never a bad thing. Gilchrist has forced at least two turnovers in six straight seasons and Bob Quinn has said he wants more playmakers on defense.

Andrew Adams, Tampa Bay Buccaneers: The Bucs reportedly won't tender Adams as a restricted free agent, which will make him free to sign with any team come 4 p.m. Wednesday. He played on the same Giants defense the Lions have raided for Damon Harrison, Devon Kennard and Romeo Okwara, and he's been a solid special teams player throughout his career.

Bashaud Breeland, Green Bay Packers: Last year was mostly a lost year for Breeland, but he was one of free agency's more coveted cornerbacks before a foot injury nullified his contract. If the Lions are serious about getting another outside corner with size, Breeland at least deserves a look.
