(Continuing a month-long series analyzing Buffalo Bills players who are on the roster bubble and where they potentially fit in 2014.)
Name: Evan Rodriguez
2013 stats: 7 games (no starts), five special teams tackles
Chance of making 53-man roster: 45 percent
Why he should make it: Fullback is a unique position in football given that that defenses need to account for him running, catching, or blocking on any given play. Rodriguez offers more of that "triple threat" than his main competition, Frank Summers. Whereas Summers is more of a pure lead-blocker, Rodriguez is smaller but more mobile and could have a role in the Bills' up-tempo offense. Rodriguez also provides value on special teams, adding five tackles in seven games last season.
Why he shouldn't make it: The Bills may not have room for Rodriguez, a former fourth-round pick. The additions of Bryce Brown and Anthony Dixon will likely cause the Bills to carry four running backs, so adding two fullbacks to the roster -- Rodriguez and Summers -- might be too much. Rodriguez's chances could also be hurt if the Bills decide to carry four tight ends, including Chris Gragg, on the roster. With the team expected to keep as many as six wide receivers, other spots at skill positions will come at a premium and Rodriguez could lose out.
Closest competition: Summers, Gragg, T.J. Graham
