Players participate in the camp by invitation only. Williams received an invitation from his agent, Rob Pelfrey, who founded the camp. The camp consists of a two-week preparation period of punting and drills in preparation for the final day. The culmination of the camp is a one-day tryout with NFL scouts in attendance. During this time leading up to the final day, the punters work on technical drills which focus on using the proper in-line steps and ball release.
Punters have to surpass a minimum standard of punting distance and hang time to make the final cut.
Williams indicate that the bar was set to about 40 yards and a hang time of about 4.2 seconds a year ago. Williams estimates that he averages about 44 yards per punt with a hang time of 4.3 to 4.4 seconds. Those numbers would rank him near the top of the NFL's punting leaders. Denver's Tom Rouen and Minnesota's Mitch Berger led their respective conferences with 46.5 and 45.4 averages, respectively. Twenty-four NFL teams sent scouts to the camp last year.
