(Continuing a month-long series analyzing players who are on the roster bubble and where they may potentially fit in 2014.)
Name: Chris Gragg
Position: Tight end
2013 stats: 9 games (one start), five receptions, 53 yards, one touchdown
Chance of making 53-man roster: 45 percent
Why he should make it: The Bills invested a draft pick in Gragg just over a year ago. He's the most athletic tight end on the roster but was used sparingly last season. With what was essentially a "redshirt" NFL season under his belt, perhaps Gragg is ready to take the next step this season. Even if Scott Chandler and Tony Moeaki are locked into roles at the top of the tight end depth chart, Gragg could stick as depth at the position. Having a young prospect in the pipeline isn't a bad thing.
Why he shouldn't make it: Moeaki's addition last December didn't initially push Gragg off the roster, although it could have. The Bills carried four tight ends through the final month of the season, with Moeaki still being eased into the offensive system. If Moeaki becomes a bigger contributor this season and the Bills keep Chandler and Lee Smith on the roster, as they are expected to do, then there might not be a spot for Gragg. Keeping four tight ends could be difficult if the Bills carry four running backs, a fullback, and six wide receivers, as they could do. Gragg's best shot to stick might be by earning a spot on the roster over a fullback or receiver.
