Each of these players will be fighting just to make it through the roster and into training camp. It wouldn't be a surprise if any of them were cut to make room for another move throughout the summer (such as former Army linebacker Josh McNary, who has yet to arrive in Indianapolis and does not currently count toward the 90-man limit).
It's a combination of undrafted free agents, fringe veterans and roster-fillers, and any of these players would be ecstatic to make the final roster.
90. Dan Moore, FB: Moore is a camp body at fullback and nothing more. It wouldn't be completely unheard of if he beat out Stanley Havili for what will be the lone FB spot on the roster, but it would be one of the biggest shocks of training camp.
89. Rick Schmeig, C: Schmeig was brought in after the team traded A.Q. Shipley to Baltimore for a conditional seventh-round draft pick in 2014, and he will simply be the third-team center in training camp.
88. Lanear Sampson, WR- Sampson was a UDFA signing immediately after the draft, and will compete for one of the final wide receiver spots, but other signings either have more experience or offer more.
87. Marshay Green, CB: Green has bounced around the Colts and Cardinals' practice squads over the last few years. Could he make the leap to the active roster for a substantial amount of time this year? My gut says the Colts know his limitations and will take a shot on someone else.
86. Davin Meggett, RB: Meggett has experience on the Colts and Texans' practice squads, but Delone Carter and Kerwynn Williams should be the two competing for the third running back spot.
85. Delano Howell, S: Howell contributed on the Colts special teams for a few games last season but wasn't particularly productive and should be a first-round cut in training camp.
84. Denodus O'Bryant, RB: An undrafted free-agent signing, O'Bryant is the Lindenwood all-time leader in rushing yards and touchdowns and was an NAIA All-American twice. But he'll have an uphill battle to beat out Carter or Williams for a spot on the roster.
83. Larry Asante, SS: He's played on special teams for Tampa Bay in the past but wasn't in the league in 2012, and defensive backs have a lot of competition for those fringe spots.
82. Allen Chapman, CB: "Bubba" played well enough in rookie minicamp that the Colts cut his former teammate Nigel Malone and signed Chapman, who was only at minicamp on a tryout basis. He'll need to have an equally impressive offseason and training camp to stick in Indianapolis.
81. Brandon McManus, P/K: McManus can both punt and kick for the Colts, which has value, but his main spot is kicker, which has prompted fans to question whether Adam Vinatieri's job is secure. Don't worry, it is. McManus is a camp leg, and that's it, unless something tragic happens to Vinatieri.
80. Quinton Spears, LB: Spears played for the Browns in 2011 but was cut in the final wave last August. Nobody picked him up throughout the season, but the Colts signed him in January to compete as a special teams/depth linebacker.
79. Monte Simmons, LB: Last season, Simmons was snatched up by the Colts in October to fill out their practice squad, where he lasted all season. That consistency is key for the young LB, who has familiarity with the team and staff that could be invaluable in August.
78. Caesar Rayford, LB: Rayford was recently signed in place of LB Jake Killeen. Rayford has been an Arena Football League player over the past three years after failing to stick in the NFL. Rayford will compete at OLB, and his size and history of blocking kicks on special teams make him an interesting prospect.
77. Rodrick Rumble, WR: Aside from having a fantastic name, Rumble left Idaho State as the Bengals' all-time leading receiver. Rumble uses his size well and has good hands, but a limited route tree in college may hurt his chances at sticking in the NFL.
76. Jabin Sambrano, WR: The Colts signed Sambrano as an undrafted free agent last offseason, and he made the final roster but was cut just a few weeks into the season. Nobody picked him up until the Buccaneers did in December, but the Colts thought enough of him to sign him to a future contract in January, wishing to see him compete in training camp again.
75. Jeremy Kelley, WR: The 6'6" receiver has played in both the Canadian and Arena Football League over the last two years and has size that is unheard of in Indianapolis. The Colts lack height at wide receiver, and Kelley may be a big red-zone target worth a final roster spot.
74. Scott Lutrus, ILB: Lutrus played on the 2011 Colts after being picked up off the Rams practice squad, participating in four games. But he was on injured reserve for all of 2012, and the current Colts have much better depth at ILB than the 2011 team did. Lutrus will have to impress to make the roster in 2013.
73. Robert Griffin, G: Griffin has experience in the NFL and with the Colts, but it's limited to offseason and practice-squad work. The Colts have a lot of competition at interior line, but his overall talent is limited, leading to the former sixth-round pick's spot here.
72. Daxton Swanson, CB/S: Swanson turned some heads over the last few weeks in Indianapolis, playing his way into the coaches' eyes. Swanson has a shot at the final roster as a fourth or fifth corner, and the way he's played so far is exactly the way an undrafted free agent has to in order to make that leap.
71. Sheldon Price, CB: Much like Swanson, Price's play in rookie minicamp and OTAs have led him to be one of the undrafted free agents with the best chances of making the final roster.
