If Marcus Mariota and the Titans had gotten a touchdown on that last possession (instead of being sacked by Andre Branch on the last play of the game), it would be incredibly tough for the Jaguars to win the division and sneak into the playoffs.
Instead, Branch and the rest of the Jags defense stepped up and the Jacksonville Jaguars are now 4-6 and still in the running to take the division crown. The playoffs are still a very real possibility, but the Jags need to keep winning and things need to go right for this franchise over the next few games.
