Over the past 30 years, the NFL has turned what was just hours and hours of a bunch of old guys in suits in a hotel ballroom into a national prime-time red carpet Radio City Music Hall gala event.
What happens after the fanfares fades and the Klieg lights go dark, though, hasn't changed one bit.
Across the nation, some college football players are glued to their phones, waiting desperately for a team, or their agent, to call. Others are wielding multiple phones, frantically comparing contract offers and depth chart outlooks and weather and tax rates and living situations, hoping they make the right choice for what might be their only shot to play football for a living.
On the other end of the line, teams like the Green Bay Packers started working the phones during the final rounds of the draft, calling small armies of prospects trying to gauge interest, availability and contract demands.
Somehow, these players and teams settle on each other, and somewhere between a handful and a couple of dozen undrafted free agents come to every NFL team's camp every season.
Here at Bleacher Report, we're keeping track of all of these crazy, quickie deals so you don't have to work your phone into overtime like the teams and players do.
