It usually starts the 3rd Friday in August or the 4th Friday from looking back to 2018 & 2019. Both years had 5 Fridays. With the 10 game schedule, I think no change will be made. This lets the playoffs end a week early or 2 weeks if no 11 week season allowing for an open week which was a 12 week season with 11 games plus an open week. All this depends on how they set up the start date and a 10 week or 11-week schedule .
