Not every player that makes an NFL roster is drafted.
Each and every year a handful of players on every team make it the hard way, via free agency (see Shields, Sam).
So far 4 undrafted 'Canes have been inked contracts with NFL squads:
QB Ryan Williams - Cincinnati Bengals
C Shane McDermott - Dallas Cowboys
LB Thurston Armbrister - Jacksonville Jaguars
DT Olsen Pierre - Chicago Bears
Updated: QB Jake Heaps - New York Jets
Williams would seem a long shot to stick as Andy Dalton's back-up and/or a #3 on the Bengals roster. Out of the group above I like Armbrister's chances the best as he can play Special Teams and possibly be a situational pass rusher.
Thus far we have not heard of CB Ladarius Gunter signing anywhere. This is something of a surprise considering Gunter has been considered a potential late round pick in the draft.
Updated: Gunter was signed late Saturday evening by the Green Bay Packers
We'll be sure to provide updates as we learn them.
