2013 Eric Herman, 7th Round (New York Giants)
2012 LaVon Brazil, 6th Round (Indianapolis Colts)
2010 Taylor Price, 3rd Round (NE Patriots)
2009 Mike Mitchell, 2nd Round (Oakland Raiders)
2008 Landon Cohen, 7th Round (Detroit Lions)
Another way of looking at these guys is based on the recruiting classes:
2001 - free agent - Byrum
2002 - free agent - Muncy, Mayle, Wright
2003 - free agent - McRae
2004 - Landon Cohen, 7th Round (Detroit Lions)
2005 - Mike Mitchell, 2nd Round (Oakland Raiders), CFL - Chris Garrett, free agent - Mark Parson
2006 - Taylor Price, 3rd Round (NE Patriots), free agent - Julian Posey
2007 - LaVon Brazil, 6th Round (Indianapolis Colts), free agent - Noah Keller
2008 - Eric Herman, 7th Round (New York Giants), [Travis Carrie???], Arena Football - Boo Jackson, free agents- ?
2009 - [Donte Foster????], free agents - ??
2010 - doubtful
I'm sure there are more that have signed free agent contracts than I have listed. My memory is hazy, however.
