If not, I think the NFL will just dump it in the next CBA to add those 4 games to the Reg season and create more excitement for fans watching.
Today's players are in shape year round and do NOT need what the PS was intended for decades ago. imo
Just make the NFL product/experience more exciting by streamlining the games and dumping things that do NOT matter.
If the NCAA can get ready for the season without a PS...why can't the NFL???
btw - they play 20 games anyway..they just don't count/add the 4 PS games to the existing 16 reg season games.
