Continuing a month-long series analyzing players who are on the Buffalo Bills' roster bubble and where they potentially fit in 2015:
Name: Bacarri Rambo
2014 stats: 4 games, 2 tackles, 2 interceptions
Chance of making 53-man roster: 75 percent
Why he should make it: With Aaron Williams recovering from offseason surgery and not practicing during OTAs and minicamp this spring, Rambo saw the majority of first-team reps next to Duke Williams at safety. With Corey Graham and Jonathan Meeks the second-team duo at the position this spring, Rambo finds himself in an advantageous spot entering training camp. Duke Williams is the favorite to remain as a starter at safety when Aaron Williams returns, but Duke Williams' role is hardly guaranteed, giving Rambo a shot at the starting gig this preseason. In either case -- as a starter or top reserve -- Rambo is a stronger bet to make the 53-man roster.
Why he shouldn't make it: The knock against Rambo during his abbreviated stint with the Washington Redskins was his tackling ability. The Bills see potential in the former sixth-round draft pick to clean up his tackling issues and become a better all-around safety, but if he can't, Rambo becomes a liability in the back end of the defense. Should Aaron Williams and Duke Williams lock down starting spots and Graham become the first safety off the bench in sub packages, then Rambo must make his mark on special teams. In that scenario, he could lose his job to another safety with special-teams prowess -- Meeks or Kenny Ladler -- or the Bills could opt to keep an extra cornerback such as Ron Brooks to help on special teams.
Closest competition: Meeks, Ladler, Brooks.
