Packers’ defense seeking to avoid ‘roller coaster moments’

As long as the Green Bay Packers keep scoring 40-plus points every game, their defense can afford the occasional lapses that have marked their first two performances. ”We can’t have any up-and-down moments, any roller coaster moments where we start off good and then we have our dips and then come back up,” outside linebacker Preston Smith said. Green Bay gave up touchdowns on the last three possessions of a 43-34 victory at Minnesota and the first two drives of a 42-21 victory over Detroit.
