rest - https://www.denverbroncos.com/news/s...ack-in-the-dayThe Denver Broncos have concluded their offseason workout programs, and players and coaches are currently some time off over the next month before the rigors of the NFL season truly begin.
The league year has expanded over the last couple of decades and now, between lifting and various camps, being an NFL player became a full-time job — but it was not always so.
For much of the first century of pro football, the game was largely a six-month job.
Believe it or not, but once upon a time there were no offseason programs in the NFL. There was no official lifting program, and many teams did not even have weight rooms.
Back in the day, before salaries and traning sophistication were what they are now, players often had to supplement their NFL wages with another job of some sort.
