"This is a potential Super Bowl matchup," Reed said.
The Texans (2-1) will host the Seahawks (3-0) in their first of four games against NFC West teams. The matchup sits in a challenging stretch for Houston, a week after its 30-9 loss to the defending Super Bowl champion Baltimore Ravens and preceding a game against the defending NFC champion San Francisco 49ers.
"We had to make a lot of corrections this week, Monday, which we did to get better," Reed said. "You can't win them all. We know that now."
Sunday's game will feature the defenses ranked first and second in total defense and passing yards allowed. The Texans have given up 249 yards per game, while the Seahawks have allowed 241.7 yards per game.
Asked if facing the top-ranked defense is motivating, Reed said it was.
"Of course, of course, but [Houston's D is] not playing against their defense," Reed said. "We're playing against their offense and we've gotta execute our plan to give our team the best opportunity to win on offense and special teams."
