The Record: week 6, and the Rams lost a two-point game with 47 seconds left

Seven calls right. Seven wrong. A flat coin flip, the second soft week running after last week’s 9 of 15, and the week’s defining moment came down to a single flag with under a minute on the clock. The headline miss Los Angeles Rams were the heaviest favorite to lose all week, 82.9 percent at […]

NFC West Cutdown: Aaron Donald Is Back, and the Flag Ledger Has Notes on Everyone Else

The biggest transaction of cutdown weekend anywhere in football happened in this division, and it was not a cut.

NFC South Cutdown: Atlanta Shed Its Holding File, Carolina Signed a Roughing the Passer Record

Denver Five out, four in, the only team in the division that added more than […]
