With the start of the 2017 league year, the NFL altered its traditional format for trimming down rosters from 90 to 53 players.
The old format was as follows:
- 90-man roster for preseason weeks 1-3
- Trim roster from 90 to 75
- Participate in week 4 of the preseason
- Trim roster from 75 to 53
The new format is as follows:
- 90-man roster for the entire preseason
- Trim roster from 90 to 53 after week 4
This all seems just fine.
