Even in that game, Michael Thomas, Ben Watson, Kamara and Ingram were all playing and the Falcons gave up four turnovers.
The Saints played several bad weather games, with better receivers, in Carolina and Tampa during Brees' tenure. They typically ended up with scores like 16-14 and both teams looked sloppy. That's just how games like that usually play out. Holding 2-3 bad throws against Winston and ignoring at least 5 passes that hit receivers in the hands and were dropped is a ridiculous double standard.
