There it is again, the Saints excuse. No one moans about the Rams preceding series when Goff's head was nearly yanked off by a blatant facemask that would have given the Rams first and goal at the NO-1, which likely results in a touchdown and a 4-pt Rams lead. Thus, NO's follow-up series is completely changed needing a touchdown or lose. But let's say all plays still unfold and the missed DPI is called, the Saints could not have milked the clock for a GWFGA. They would have a first and goal at the LAR-6 with around 1:45 to play and 2 TOs to use. The Saints may have scored a TD for a 3-pt lead but the Rams likely would have had time to get in range for a tying FG. Conversely, the Rams may have stuffed the Saints and forced a turnover on downs.
I'm all for calling out missed penalties and bad calls but this Rams/Saints game is one that only one-call is ever recognized despite a preceding series no-call had just as much effect on the outcome.
