Dak, Parsons, Martin, and Diggs should all make the day 1 roster with no issues.
Zeke is REALLY lucky because the top 4 rushers in the league right now are all in the AFC. Since they do NFC and AFC seperate he should easily get in as well (he's 2nd in the conference in yards and touchdowns).
If Tyron plays the next 4 games then he will be a day 1 lock as well (him and Trent Williams are locks for NFC tackles).
