In short

R Mason Thomas is a starter at right defensive end for KC — 60% of the snaps in his best week of 7. He has a not injury related - personal matter injury. His snaps dropped last week. Of players in that position who did play the following week, 43% took under 70% of their usual snaps. In week 8 he did not practise. His team has listed him Questionable.

The reader dissents · grade A · superseded

The sole absence is a non-injury personal matter that cost him only Friday's practice, and the club listed him Questionable rather than doubtful or out (P1). — Our call has since changed from SIT to PLAY. This reading was written against the earlier one and is kept as it was; it is not an argument about the call shown above.

The reader's full reasoning

The rest of the reading

The head coach spoke directly to this Sunday's Denver game: "On Friday, Andy Reid said Thomas will meet the Chiefs in Denver and will likely play" (P1) — the club's top voice outranks the generic Questionable/DNP cell the model priced, and a personal-matter DNP carries none of the physical risk the cell's base rate reflects. The practice axis (DNP) is not the game-status axis here, and the only game-status signal available points to playing (P1).
