Think these unselected athletes don't matter?
Think again, last year more than 30 percent of pro players had started as undrafted free agents.
A Penn State specific example, Matt McGloin, ended the year as the Raiders starting QB.
The latest former Nittany Lions to get a chance as free agents are Malcolm Willis and Adam Gress.
Willis heads to rookie camp with the San Diego Chargers at safety.
Gress is Pittsburgh bound, earning an invite from his hometown Steelers.
