Patrick Butrym signed as an undrafted free agent with the San Francisco 49ers. The 49ers have a deep defensive line led by Justin Smith, and it is doubtful that Butrym makes the active roster. Butrym likely ends up on the practice squad, and only receives playing time following an injury.
Louis Nzegwu signed with the Atlanta Falcons as an undrafted free agent. Nzegwu faces a similar situation to Butrym as the Falcons have a deep and experienced defensive line. The return of John Abraham forces Nzegwu to the practice squad.
Aaron Henry, an undrafted free agent, signed with the Oakland Raiders. The Raiders are deep at the safety position with four free safeties on the roster along with Henry. It is doubtful Henry overtakes incumbent Matt Giordano or former first-round pick Michael Huff and will likely end up on the practice squad.
Antonio Fenelus signed with the Indianapolis Colts after going undrafted in the 2012 NFL Draft. The Colts are in rebuilding mode following an awful 2011 season and have holes all over the roster. With nine cornerbacks currently on the roster, Fenelus has his work cut out for him and will probably end up on the practice team.
Josh Oglesby is another undrafted free agent who will almost surely make the practice squad. Oglesby signed with the Redskins after being undrafted in 2012. Oglesby, who does have NFL size, probably won't beat out enough of the nine tackles that the Redskins have to make the active roster. A spot on the practice team is almost assured.
Jake Byrne decided to sign with the New Orleans Saints after the 2012 NFL Draft. The Saints only have four tight ends on the roster. With All-Pro Jimmy Graham entrenched as a starter, Byrne could make the active roster depending on how many tight ends the team carries. Even if he does make the active roster, he probably won't see much playing time.
