I just went back through and I didn't see any discrepancies. I haven't updated Sunday's game yet, and here are the totals prior to the Redskins game:
2019 New England Patriots Opponent Stats | Sortable 3rd Down, Red Zone Passing and Rushing Opponent Stats.
Sunday's total appears to still be 6, so the 24 total is accurate because they did have 18 coming into Sunday.
These are the totals:
vs PIT - 1
@ MIA - 7
vs NYJ - 5
@BUF - 5
@WAS - 6
I haven't touched my spreadsheets since each game ended, so mine are still original and they match the current totals, so I don't see any removed. The one thing I did notice is there was additional one credited at some point after the 2nd quarter because they corrected a play at 9:11 (QTR2) where it wasn't a sack initially and it later became a sack with a declined penalty (I think they had it originally as a nullified play [no sack] by a holding penalty) - which wasn't in their system that way in real time. I grab it off the feed, so if I did - other outlets probably did also. But that's the only thing I noticed.
