The Detroit Lions have made a move to improve their secondary. They have signed Rashaan Melvin to a one-year deal and he will likely get a chance to start in some capacity.

This news comes from Adam Schefter via Twitter.

Melvin's one-year deal is worth $3.5 million and is likely a “prove-it” deal after playing for multiple teams over his six-year career. Most recently, Melvin spent the 2018 season with the Oakland Raiders.

In 2018, Melvin started in seven games where he had 56 tackles, nine pass deflections, and one interception. This comes after getting 36 tackles, 13 pass deflections, and three interceptions with the Indianapolis Colts in 2017.

The Lions lack depth in their secondary, let alone their cornerback position. Besides Darius Slay, there isn't one guy who is guaranteed to start at cornerback.

The Lions' pass defense ranked 11th against the pass in 2018. They're hoping the addition of Melvin can help them crack the top 10 in the NFL in 2019.

The area where Detroit is hoping that Melvin can improve is the interception column. In 2018, the Lions struggled to intercept the ball and were ranked 29th in the NFL with only seven interceptions.

The past couple of seasons, Melvin has shown the potential of being a guy who has good ball skills. Therefore, signing him should help the defense get more opportunities for their offense and Matthew Stafford.

Although it's not a big-name signing, signing Melvin can be an underrated move when the 2019 season is over. Detroit fans should be excited for the potential of the defense after adding Trey Flowers as well.
