Our ranking countdown of the Green Bay Packers' 90-man roster continues this morning, as we move into the sixties. While most of the players here are still in the undrafted free agent class, we find our first players from last year's active roster as well as the first member of the Packers' 2015 draft class.

Here are players 70 through 61.

70: Jeremy Vujnovich, T

Up 11 spots from this time last year, Vujnovich spent the entire 2014 season on the Packers' practice squad. As such, his familiarity with the offense should help him earn some second-team reps in training camp. He played almost every snap of last year's fourth preseason game at left tackle, and was just okay.

69: James Vaughters, OLB

Coming from a Stanford program that runs a 3-4 defense, Vaughters' transition to the Packers' system is likely to be quicker than that of many other young linebackers. As a senior last year, he had 6.5 sacks and 11 tackles for loss. However, the veteran group ahead of him will require him to make waves on special teams to earn a spot on the team.

68: Adrian Coxson, WR

Coxson possesses elite speed (4.28-second 40 at his Pro Day), and actually has good size as well (6'1", 209 pounds). Those qualities make him a big-play threat, and he could become the next practice squad hero in Green Bay, as it is unlikely that any undrafted wideouts will crack the 53-man roster this year.

67; Bruce Gaston, DT

Added to the roster late in the 2014 season, Gaston was not activated on game day at any point. He spent training camp with the Cardinals and was then picked up by the Patriots and Dolphins before two stints on the Cardinals' practice squad late in the year. The Purdue product looks to fit best at right end behind Mike Daniels, but has not made much noise yet this offseason.

66: John Crockett, RB

Arguably the most exciting undrafted free agent signing this year, Crockett's production at North Dakota State speaks for itself (1,994 rushing yards, 397 receiving yards in 2014). He brings that intriguing blend of rushing and receiving skills to Green Bay. However, he suffered a minor ankle sprain late in minicamp, but expects to be back to full strength by the start of training camp in his effort to earn the third running back job.

65: Matt Rotheram, G

Rotheram comes from a Wisconsin Badgers-like power rushing attack at Pittsburgh, having played under new Badgers coach Paul Chryst. He was Pro Football Focus' top-ranked run-blocking guard in college football last year, but will need to work on his pass protection to stick in Green Bay. Still, he will have a chance in camp to unseat Lane Taylor as the backup interior lineman.

64: Lane Taylor, G

Taylor is a two-year Packer, but failed to impress in his brief stints filling in for Josh Sitton and T.J. Lang. Subbing in for Lang for most of the Saints game last year, he especially struggled in the run game. With JC Tretter and Don Barclay both likely able to fill in at guard and Rotheram on his heels, Taylor will need a good performance in camp to keep his job.

63: Matt Blanchard, QB

One of the surprises of the offseason was Blanchard's ability to absorb the Packers' offense and his performance in practices, especially late in the program. Most beat writers and analysts described him as being significantly better than fifth-round pick Brett Hundley in practice, but he does not have nearly the athleticism or natural ability that Hundley does, and that potential is what keeps the UCLA product ahead of this former UW-Whitewater quarterback.

62: Demetri Goodson, CB

Goodson's name was not among the list of young corners who have caught position coach Joe Whitt's eye during OTAs. Instead, it appears that he has been passed over by draftees Damarious Randall and Quinten Rollins, as well as undrafted rookie Ladarius Gunter. Goodson has a chance to stick on the roster with his special teams play, but he appears to be falling behind on defense.

61: Aaron Ripkowski, FB

The first of the Packers' draft picks on our countdown, Ripkowski seems targeted as the heir apparent to John Kuhn, but on offense that transition may have to take place gradually. Like Kuhn, the rookie from Oklahoma should have plenty of special teams opportunities, and appears poised to impress there while he works his way into the offense.

Next up this afternoon: players 60 through 51.
