The Detroit Lions do not need to make a splashy move every time a roster question pops up.Sometimes the smartest answer is the most familiar one.With training camp placing fresh pressure on Detroits secondary depth, former Lions defensive back Ifeatu Melifonwu deserves another look. Not a guaranteed contract. Not a promised role. Just a workout and an opportunity to show Brad Holmes and Dan Campbell what he can still offer.There is very little downside.Ifeatu Melifonwu Already Knows the LionsMelifonwu would not arrive in Allen Park needing an introduction to the organization.Detroit selected him in the 2021 NFL Draft, and he spent several seasons moving between cornerback and safety. His time with the Lions featured injuries and stretches of inconsistent availability, but it also included flashes of the athleticism and versatility that made him an intriguing prospect in the first place.Mike Payton of A to Z Sports recently identified Melifonwu as a player Detroit should consider bringing in for a training camp tryout.The logic is easy to understand.Melifonwu knows the culture. He knows what Campbell expects. He has played in Detroits defensive system, understands the demands placed on Lions defensive backs and can line up at more than one position.At 27 years old, he should still have enough athletic ability to compete for a depth role.Detroit Could Use More Secondary CompetitionThe Lions may feel comfortable with the players currently competing at cornerback and safety, but training camp is exactly when teams should examine every reasonable option.Depth disappears quickly in the NFL.One injury can change a players role overnight. A second injury can force a team to rely on someone who was expected to spend the season on the practice squad.Melifonwu would give Detroit another experienced body capable of working at safety, cornerback or in certain matchup packages. That flexibility would be especially useful during camp, when coaches are evaluating different combinations and trying to determine which reserves can handle multiple assignments.He would not need to become a starter for the move to make sense.If Melifonwu proved capable of helping on special teams, filling in at multiple spots and providing veteran insurance, he could make the bottom of the roster more competitive.His Previous Detroit Tenure Was ComplicatedThere is a reason Melifonwu remains available.His first run with the Lions never developed into the steady, long-term role the organization once envisioned. Injuries interrupted his progress, and his best stretches were too often followed by additional time away from the field.Detroit eventually moved on.That history should not disqualify him from receiving another opportunity. It should simply shape the expectations.The Lions would not be bringing him back to reclaim a starting job. They would be evaluating whether a healthy and experienced Melifonwu is better than one of the developmental defensive backs currently fighting for a roster spot.That is a question worth answering on the practice field.Melifonwu Has Continued Seeking Another OpportunityMelifonwu has remained active in his effort to return to an NFL roster.According to Payton, the former Lions defensive back has recently worked out for the Tennessee Titans and Seattle Seahawks. He also spent time with the Miami Dolphins and reportedly played well during that opportunity.No team has signed him yet.That could work in Detroits favor.Melifonwu would likely come with a modest price tag and little financial risk. A tryout would cost the Lions almost nothing, and even a short-term camp contract would not prevent Holmes from pursuing another option if one becomes available.This is the kind of move good teams make around the edges.Bring in competition. Let the player prove he belongs. Make the roster stronger without attaching unnecessary expectations.The Jameson Williams Scuffle Should Not MatterMelifonwu returned to Allen Park last year as a member of the Dolphins during joint practices and became involved in a brief confrontation with Lions wide receiver Jameson Williams.Training camp scuffles attract attention because cameras are everywhere and fans are eager for any sign of intensity. Most disappear as quickly as they begin.Payton described the incident as the kind of competitive exchange that happens between players during emotional practices. There is no reason to believe it would prevent Detroit from considering a reunion.Camp is hot. Players are tired. Jobs are on the line.Tempers occasionally flare.Unless the Lions know something more serious about the incident, it should have no impact on whether Melifonwu receives a workout.Familiarity Makes the Evaluation EasierDetroit would have a much clearer picture of Melifonwu than it would of most available free agents.The Lions know his strengths. They know his medical history. They know how he responds to coaching and whether he fits inside the locker room.That familiarity can cut both ways. Perhaps Detroit has already decided that another reunion is not worth pursuing.Still, circumstances change.A player who did not fit one version of the roster may make sense for another. A former starter may become a useful reserve. A defender who once needed developmental snaps may return with enough experience to handle a narrower role.There is no harm in checking.Bottom LineThe Detroit Lions should bring Ifeatu Melifonwu back to Allen Park for a training camp tryout.He already understands the organization, can play cornerback and safety, and remains young enough to compete for a role. His injury history and uneven first stint with Detroit are valid concerns, but neither should prevent the Lions from taking another look.A workout carries almost no risk.If Melifonwu has something left, Detroit could add inexpensive and versatile depth to its secondary. If he does not, the Lions move on without losing anything.Sometimes the obvious move is obvious for a reason.
