Brandon Myles: Expected to be drafted the during the second day of picks, Myles never received the call. He attended both Giants and Falcons mini-camps but was waived before the 2007 season ever began.
Dan Mozes: After a highly touted career at WVU, center Mozes went undrafted. Though many worried his size would not allow him to carry over into the NFL, the Vikings picked him up. Mozes injured his knee at the beginning of the season and never had a chance to play. He was invited back to the Viking's camp the following year, but was waived before the beginning of the 2008 season.
Cleo Kevin "Boo" McLee: You know who's hard to research? People with three first names. Mclee went undrafted but was picked up by the Rams as a linebacker. That summer, his father passed away and he left the Rams. Shortly afterwords, he was arrested with intent to deliver cocaine and marijuana. He received one year probation for the incident.
From there, the record becomes a bit fuzzy. Wikipedia says he went on to play in the CFL with the Calgary Stampeders but has no references. In 2008, it looks like he played in the Arena Football League 2 (a sort of farm league for the AFL) with the Iowa Barnstormers and the Green Bay Blizzards.
Most recently, he was drafted by Louisiana in the newly made United National Gridiron League.
Jeremy Sheffey: The Chargers picked up Offensive Guard Sheffey after the draft. He was given a two year contract but was released before the beginning of the season after an injury.
Sheffey was also picked up by the AFL 2's Blizzards. After a short stint with the AFL's New York Dragons in 2008, he returned to the AFL 2 and the Blizzards but was released after an injury.
