It used to be anyone with an accrued season was not eligible. This is now TWO years. This is amazing to me. Great idea.@AdamSchefter: By next week, NFL is expected to increase size of practice squads to 10 players from 8, per source. So 64 more jobs.
Basically if you're on a roster for 9+ weeks in a season, that's a season. I think 6 games active 46 also is the same. But now you can do that for two years and still go to the PS.
