3. Rams pass defense vs Andrew Luck

Another huge test for the Rams pass defense as they welcome in Andrew Luck who had the best passing attack last year with 305.9 passing yards per game. The last few years, the Rams defense has allowed opposing quarterbacks to have their way on offense. With Luck in town, the Rams will get to prove themselves facing the top passing offense in the league. Luck is known for his deep balls, and for this game I see Fisher not focusing on completion percentage, but how many touchdowns they give up. As long as the Rams don’t allow that many touchdowns like they have the first two preseason games, its a win for the defense. Limiting passing touchdowns for Luck would be a great win for the defense.
