Undrafted free agents signed by the Baltimore Ravens don't have the same expectations as they do around the league. The Ravens have a history of finding gems that fall through seven rounds because they're not big, strong, fast or skilled enough. Furthermore, the Baltimore coaching staff rewards hard work and good play, which means that all of the UDFAs on the roster right now have a chance to latch on with this team.
It would be unrealistic, of course, to suggest that all of them make the practice squad (there isn't enough room) let alone the final roster. And with a ton of priority free agents on the roster—the by-product of an exceptionally deep draft—they are competing against each other for the reward of an extended stay in Baltimore.
This list will break down the players' strengths, weaknesses and the roles they would fill on the team to give you an idea of what to keep an eye on during OTAs and training camp. Moreover, the players are organized by likelihood of making the team (starting with the longshots and ending with some players that stand a very good chance of making the final roster).
Make sure you remember these names. If history is any indicator (and it usually is), at least one of these free agents will be a diamond in the rough.
