Life in the NFL boils down to one thing: making the roster.
This is true for all, but especially for rookies. For some, the NFL Draft opens up a lane toward that end goal. For others, an invitation to walk on is all they can ask. It's then up to them to prove their value come autumn.
Making it as an undrafted rookie is no easy task, but it is possible. From Hall of Fame defensive back Emlen Tunnell to wide receiver Victor Cruz, undrafted players make rosters every year, and 2015 likely won't be any different.
Here's a look at undrafted rookie free agents who have made the final cut in Tom Coughlin's tenure with the New York Giants:
