Earlier this month, a shipment consisting of three large cardboard boxes arrived at DeMario Douglas’s locker. Inside were hoodies for his teammates with the locker room’s new slogan, “We All We Got/We All We Need!”

Its origin dates to Week 5, when the Patriots beat the Bills. As part of his fiery speech on the field before kickoff, wide receiver Stefon Diggs told the team, “Lean on your brother. Play for your brother. We all we got. We all we [expletive] need. Play hard. Play smart.”

Then, after the Patriots pulled off the upset and coach Mike Vrabel had addressed the team inside the visitors’ locker room at Highmark Stadium, Diggs broke down the huddle by saying, “We all we got!” To which his teammates said, “We all we need!”

The players have embraced the mantra over the past six-plus weeks, even more so after the front office didn’t acquire any talent at the trade deadline.
