Former NFL quarterback Trent Dilfer believes that the defense of the Titans may just be as good as that of the 2000 Ravens. Dilfer, now an analyst for ESPN, was the quarterback of Baltimore's 2000 team. "The profile is very similar. Four games into the 2000 season, that was a very good Ravens defense that just kept getting better. The challenge for Tennessee is whether they can continue to improve," Dilfer said. "I would not say right now they are as good as the end product of the 2000 Ravens. But they're the first defense I've seen that has the potential to have the same end product." Tennessee has allowed just 46 points through the first four games of the season, and stand at 4-0.
