The clock keeps ticking toward the start of training camp, if it’s indeed going to start on July 28. Aiding that process would be an agreement between the NFL and the NFL Players Association on all remaining issues. There are several.

Per a source with knowledge of the situation, the significant sticking points are listed below.

1. Testing: The NFLPA wants daily testing. The NFL continues to resist that approach. The source says that daily testing is a “big, big issue.”

2. Acclimation period: The NFLPA wants to gradually phase players in physically, given that there was no offseason program and limited opportunities for players to work out as they normally would.
