Answer based on context:

The Patriots rebounded from their opening week loss by establishing an early insurmountable lead against the New Orleans Saints in their week 2 matchup. Brandin Cooks returned to the Bayou while the controversy surrounded Saints running backs Adrian Peterson and Mark Ingram (at this point Kamara wasn't part of the argument) over touches. Peterson would later be shipped to the Cardinals in an ironic turn of events for Chris Johnson. Tom Brady completed three first-quarter touchdown passes to Rex Burkhead, Rob Gronkowski, and Chris Hogan. The three touchdowns marked a personal record for Brady, who had never in his career had so many scores in the first quarter of any game. Mike Gillislee added a running touchdown in the second quarter, and the Patriots played a conservative second half to seal the 36-20 victory. Grownkowski injured his groin in the third quarter, causing him to leave the game.
