It was the Texans game, in Week 5, that convinced me.
The Falcons had fallen to 1-3 the previous week, after a lousy all-around performance against the Titans. Tennessee was up 24-7 going into halftime after Marcus Mariota eviscerated Atlanta’s pass defense and had his best game of the season. That performance alone probably bought Mariota two more weeks of starting—he was benched for Ryan Tannehill in Week 6, who looks like a pretty significant improvement.
The Texans game was always going to be a difficult one to pull off.
