Daniel Rodriguez has gotten plenty of press (here, here, and here) for his contributions during his service in the Army. He attended Clemson on the GI Bill, walking on to the football team in 2012. He was primarily a special teams player during his time at Clemson, but also dabbled as a punt returner.
It's a great story - war hero turned football player - but his uphill battle will continue if he's going to make the roster.
Roster Battle
As an active-duty service member, I want Rodriguez to succeed, but the football side of things make Rodriguez a longshot to make the team.
