The longest of long shots to make an NFL team out of training camp are the rookie free agents. Many sign with teams, but few get the shot to stick around. With rookie free agent class, that's no different. But there may be a few gems in there who have a shot to stick around.

Anthony Aldridge, RB, Denver Broncos: Mike Shanahan can turn runners into productive backs, and Aldridge may be the next. He is only 170 pounds, so he won't be an every down back, but with the way the Broncos use multiple backs, that shouldn't be a problem. Aldridge was the third leading rusher in Conference USA, and the twelfth leading rusher in the nation. Only Matt Forte (Tulsa) and Kevin Smith (Central Florida), second and third round picks, respectively, had more yards than Aldridge's 1,597. He also averaged more yards per carry than both of those players, running for over 6 yards a pop while scoring 14 rushing TD's. Aldridge can catch the ball as well, snaring 42 receptions for 428 yards and 5 touchdowns.

Titus Brown, LB, Miami Dolphins: Brown was rated high enough to be mentioned as a possible fourth round pick by some, but he would up not getting selected out of Mississippi State. Going to Miami may be the best thing for him anyway, as he'll have a chance to stick around as a 3-4 rush linebacker. What Brown does best is get behind the line of scrimmage, as he led the Bulldogs and was eighth in the SEC with 8 sacks. And of his 43 total tackles, 13.5 were tackles for a loss, which ranked tenth in the conference.

Vince Hall, LB, St. Louis Rams: Hall, out of Virginia Tech, signed with the Rams when he was passed over in the draft. A middle linebacker, Hall's lack of speed probably hurt him the most, but the Rams are in need of a back-up at the position, which bodes well for him. Hall was productive in college and always around the football, finishing his senior year with 100 tackles, 6.5 tackles for loss, 3 sacks and an interception.

D.J. Hall, WR, New York Giants: Highly productive out of Alabama, Hall has good height at about 6-foot-2, and runs well. More than likely, he was not drafted due to concerns about his character. Still, Hall was fourth in the SEC with 1,005 yards receiving while catching 6 TD passes. He had some huge games, going for 172 yards and 2 TD's against Arkansas, 140 yards on 11 catches vs. Mississippi, and 185 yards and 2 TD's on 13 catches against Tennessee.

Ali Highsmith, LB, Arizona Cardinals: Everyone thought Highsmith would be drafted after his career at LSU ended. For one reason or another, probably his size, it didn't happen. But he has a chance to make the squad in Arizona. He was twelfth in the SEC and first on the Tigers with 101 tackles, and he also had 9 tackles for loss, 8 defended passes, 3 sacks and 2 forced fumbles for a national championship team.
