10-0, in the second quarter after the Titans turned a botched Trevor Lawrence pitch on an ill-advised reverse into a lead-extending touchdown drive.
Instead of missing that last step evolving teams must take to become contenders, the Jaguars found a way to win their fifth straight to capture the AFC South for the first time since 2017.
It's a night-and-day difference for a team that has picked at No. 1 overall in the past two drafts.
Those picks, QB Lawrence and pass rusher Travon Walker, both made big plays Saturday as the Jags completed their transformation.
Lawrence was essentially the entire offense considering Travis Etienne, the team's leading rusher, accounted for only 17 yards on the ground.
The second-year QB went 20 of 32 for 212 yards and one TD. Walker had a quarterback hit and four tackles
including a massive second-down tackle for loss against Titans star running back Derrick Henry in the fourth quarter
which preceded a Roy Robertson-Harris sack to force one of Tennessee's three three-and-outs in the game.
Add that big-time free-agent Christian Kirk led the team with six catches for 99 yards and a score, and you have major impacts by three key pieces in Pederson's tremendous turnaround.
Jaguars defense and special teams make the difference. Jacksonville's offense only scored two field goals in the second half and ran just 15 plays on their final four drives, excluding kneel downs.
