2. The Jaguars offense operated at full steam, Calvin Ridley was a huge factor
The Jaguars' offense is stacked with talent but they haven't been able to play up to their potential. At some point of the season, they ranked 10th in points scored but they consistently struggled to convert on third downs. To make matters worse, they had a penchant for not taking care of the ball and turning it over.
Last but not least, the Jaguars' coaching staff had struggled to make Calvin Ridley an important part of the game plan. All that changed against the Titans. Ridley exploded (not literally) with seven catches for 103 yards with two touchdowns. He also had a couple of key third-down conversions. Having Zay Jones draw coverage away from him helped, but Ridley showed what kind of playmaker he can be when given opportunities.
On a similar note, the Jaguars made the most of their opportunities, not wasting a chance to score early in the game. Sure, they punted on their first drive but once they had momentum, they didn't look back until they had built a robust lead.
It's also worth noting that the Jaguars didn't turn the ball over, the first time since Week 2 and only the second one this season. The defense, for their part, registered a takeaway one week after not getting one. Their third-down conversion could still use some work though, going 4-of-12 in such situations. Then again, Jacksonville was able to address most of the issues that held them back in previous weeks and that's commendable.
