Context: The week 3 matchup vs. the Texans proved to be a greater challenge for the Patriots than the Saints had been in week 2. The Patriots scored first on a 7-play drive ending with a Tom Brady 5-yard throw to Rob Gronkowski, who was playing with a groin injury that took him out of the previous week's game. The game would progress through seven lead changes, as Texans rookie quarterback DeShaun Watson would go drive-for-drive against Brady. Watson threw two touchdowns, one of which to his tight end Ryan Griffin, who attended college in New England at Connecticut. Two field goals late in the game would give the Texans their final lead at 33-28. With less than 2:25 remaining in the game, Brady led the Patriots on a frantic 8-play 71-yard drive that culminated in a 25-yard reception by Brandin Cooks to give the Patriots the 36-33 win.
