Could Rafael Bush departure open door for Miles Killebrew?

Rafael Bush has reportedly signed with his former team, the New Orleans Saints, leaving open the possibility of an increased role for second-year safety, Miles Killebrew. Bush was a nice role-player for the Lions last season, making some big plays in critical moments during their 9-7 playoff season.

Something defensive coordinator Teryl Austin effectively utilized in 2016 were three-safety formations in which Bush, Killebrew, and Tavon Wilson took turns playing alongside Glover Quin, Detroit’s starting free safety. It worked well because Austin put these players in a position to succeed. While each has their flaws, the team was effective using them as a platoon next to Quin.

With Bush no longer in the picture, you have to assume the Lions are happy with Wilson and Killebrew each playing expanded roles in 2017. Wilson has nice versatility and will play a key depth role regardless if he starts or not.

Killebrew, on the other hand, is a true strong safety and needs to grow in coverage to complement the rangier, more athletic Quin. If Detroit can upgrade their front seven through the draft and free agency, they may have enough young talent in the secondary to get by with the guys they have.

Darius Slay had the best season of his young career at corner, but Detroit struggled to find their number-two. Nevin Lawson made a strong case, but was often penalized for his aggressive, physical style, which he leans on as an undersized player. If Detroit sees the opportunity to add a starting caliber defensive back, I think they pull the trigger. However, the safety position may be set despite Bush leaving in free agency.

Fans grew to love the “Muscle Hammer” for his big-hit ability and knack for making key stops on third downs last season. As a fourth-round pick from Bob Quinn’s first draft as Detroit’s general manager, you have to imagine the Lions view Killebrew as a potential starter long-term.

He may not make that jump to being a starter next season, but his playing time will very likely increase — something fans will be very happy to see. Bush fulfilled his duty in 2016, but now the Lions will look to get better and younger in an improving secondary.
