The Eagles would be wise to go back to the Canadian Football League well this offseason.

After finding a special teams ace in former Calgary Stampeders linebacker Alex Singleton last season, the Eagles could benefit from adding one of his former teammates, all-star cornerback Tre Roberson, in the coming weeks.

With the Eagles likely to rebuild their secondary this offseason, the team should take an open-minded approach to re-stocking the cornerback depth chart. While free agency and the draft should be the main areas of focus, adding a cheap, up-and-coming cornerback from the CFL could be a savvy move for the Eagles.

Starting cornerbacks Jalen Mills and Ronald Darby are set to hit free agency and former Day 2 picks Rasul Douglas and Sidney Jones are in roster limbo. It wouldn’t be a surprise to see three of those four players jettisoned in March.

In order to rebuild and improve the position, the Eagles could target a veteran in free agency and a prospect in the draft. Signing Roberson would allow the team to retain some of their draft resources for other needs.

Roberson, who was a college quarterback at Indiana University and Illinois State University, could compete for a depth job to reinforce the talent at the position.

Roberson spent two seasons converting to the cornerback position in the CFL. In those two seasons, Robinson collected 95 tackles, 10 interceptions and two forced fumbles.

The Eagles’ secondary struggled to create takeaways last season and Roberson has proven he can produce turnovers at the CFL level. Adding him to the mix could be a worthwhile endeavor for a team that is set to hire a new defensive backs coach.

While Roberson is a CFL export, he has received a ton of interest from NFL teams in recent weeks.

According to ESPN’s Mike Reiss, Roberson scheduled 14 workouts with NFL teams this month. Reiss reports that Roberson will take his time with his decision and will attend each workout before signing a contract.

The Eagles are strong believers in signing players who fit into their locker room ecosystem. Luckily for the Eagles front office, the team has three players who know Roberson as a former teammate.

Singleton and practice squad holdover, wide receiver Marken Michel, played with the cornerback in Calgary. Backup quarterback Nate Sudfeld won a starting job competition over Roberson at Indiana. Roberson transferred to Illinois State in 2014 after losing the competition to Sudfeld.

While Sudfeld is set to become a free agent in March, perhaps Singleton and Michel could help recruit Roberson to join them in Philadelphia. Roberson would have a major opportunity to work his way up the Eagles’ depth chart, as a new position coach would have a fresh set of eyes on the cornerback group.

At 27, Robinson could be looking for his best opportunity to start in the NFL. The 6-foot-1, 190-pound cornerback would be a good fit for Jim Schwartz’s system, given his size, toughness and playmaking skills.
