Green Bay's coaching staff was impressed by Poppinga's high motor and relentlessness on every play. He displayed both in one of the few Packer victories of the season, a 33–25 contest against the Atlanta Falcons. Though the play resulted in an Atlanta touchdown, Poppinga displayed his range and quickness by nearly running down superstar quarterback Michael Vick on a one-yard scramble into the end-zone. Poppinga's pursuit forced Vick to stretch the play all the way to the right sideline, and only Vick's speed allowed him to dive past Poppinga and over the end zone pylon. The fact that Poppinga had begun the play at the left side of the formation displayed his unrelenting attitude and sharp instincts. In August 2006 packers' linebackers coach Winston Moss said "I'll bet he sleeps with his eyes open,", referring to Poppinga's endless energy.
