Undrafted free agents usually don't make a huge impact in the NFL, but every once in a while there is a guy that shows up and makes a big impact on a team.
For the Indianapolis Colts, they have had pretty good luck with undrafted free agents. Names like Gary Brackett, Melvin Bullitt and even Tony Siragusa weren't taken in the draft, and the Colts were able to bring them in.
This year, there are a few guys that have a real shot at making this team. Whether it's due to the fact that they are performing well at OTAs or simply because there is a big need they can fill, these guys could have a real shot at making the final roster.
Let's go ahead and take a look at a few UDFAs that could potentially make the team.
Sam Houston State certainly isn't a college football powerhouse, but Swanson is making his name known around Indy.
Plenty of people have been impressed by Swanson during OTAs, including Tom James of the Tribune-Star.
While Swanson wouldn't be an ideal corner going up against physical receivers, he certainly has the size and speed to cover guys in the slot or smaller guys on the outside. He was a raw prospect coming out of school, but Chuck Pagano is looking to develop him into a solid player.
There is probably one spot in the secondary up for grabs during training camp, and Swanson will have to go up against guys like Sheldon Price and Allen Chapman for the spot.
With how much he's been impressing at team activities, Swanson has a real shot to make the team.
Being a former roommate of Anthony Castonzo, Cleary was probably given a good word from the other former Golden Eagle.
Now that he's on the team, he needs to prove that he can stay here.
During his time at Boston College, Cleary played both left and right tackle. He did a good job on both sides, but he wasn't exceptional.
At the NFL level, Cleary will need to prove that he can either be quick enough to play left tackle or strong enough to play right tackle. He has some time to develop, but he needs to impress the coaching staff to be on the team Week 1.
Since the offensive line was in shambles last year, Cleary has a pretty good shot to come in and add some depth behind guys like Castonzo and Gosder Cherilus.
While the Colts haven't been known for their fullbacks, this year could be different with the arrival of Pep Hamilton as the offensive coordinator.
Even though Moore is listed as a fullback, he actually played a bit of running back during his time at Montana. He is a versatile player who can make plays on the ground, through the air or as a pass protection.
The best way to describe Moore is by calling him a potentially more explosive John Kuhn. He shows some nice speed and ability to pick up chunks of yards in the open field.
The Colts got Stanley Havili from the Philadelphia Eagles earlier this offseason, so Moore has plenty of work to do to prove he deserves a spot on this team.
There's something about former CFL players that Ryan Grigson seems to like a lot. He brought in Jerrell Freeman last year, and now he brought in this giant of a linebacker.
Listed at 6'7'' and 267 pounds, Rayford will likely tower over almost everyone at training camp. He was known in the CFL as a frightening defender for pressuring the quarterback, but was also known for making big plays on special teams by blocking kicks.
While it wouldn't seem likely that this guy plays as an outside linebacker in the regular season, the Colts could keep him on the roster as a guy to play on special teams, where guys like Brackett and even Robert Mathis made their name on this team in the first place.
The Colts have a few names in Reggie Wayne, T.Y. Hilton and Darrius Heyward-Bey that will be on the field often, but there are probably one or two spots open behind these guys that will feature some fierce competition during training camp.
One of the guys that will be fighting for one of these spots is Rodrick Rumble.
Even though this guy played at an FCS school in Idaho State, he had a tremendous career. He flashed some serious deep-threat potential and could make big plays in the open field by making defenders miss. At 6'2'', he makes a potentially exciting target in the red zone.
This will not be an easy task for Rumble to make the final cuts. He will have guys like Lanear Sampson, Griff Whalen and LaVon Brazill fighting with him to earn a spot on this team.
