The Jaguars playoff hopes are likely on the line Sunday against the undefeated Titans. Jacksonville lost the season opener in Tennessee. Here are the topics that we'll look forward to before the game, follow during the game and analyze afterwards:

1. Protect The Quarterback-The first time these two teams met, the Jaguars endured one of the craziest days you will ever hear about. In pregame warm ups, Mo Williams injured himself. Then Vince Manuwai blew out his ACL. At one point, Uche Nwaneri was banged up and they almost had to put tight end Richard Angulo into the lineup on the offensive line. In that game, the Titans sacked David Garrard seven times and Garrard admits that he was very sore the next day. The Jaguars offensive line seems to be more stable now that it has been all year, but last week's game against Denver wasn't much of a test. Offensive coordinator Dirk Koetter believes that the Jaguars can make some plays down the field against Tennessee. To do that, they'll have to give Garrard time.
2. Win Turnovers-Against the Titans in week one, David Garrard threw a pair of interceptions. Despite the turnovers and the offensive line injuries, the Jaguars still lost by only a touchdown. Winning the turnover battle is a big part of the Jaguars approach.
3. Run Early, Run Late-The Titans love to take away the opponent's running game. That's the bedrock of their defensive approach. If the Jaguars can run the ball early, that will open up opportunities in the passing game. That could lead to the Jaguars taking a lead, which will allow them to run the ball late. Despite going over 10,000 career yards against the Titans last year, Fred Taylor hasn't had a 100 yard game against the Titans since 2004. This is going to take Taylor, Maurice Jones-Drew, and maybe Greg Jones to get it done.
4. Unity-I believe that this week is a real test of Jack Del Rio's ability to get the team on the same page. Considering Del Rio's call to circle the wagons earlier this week (he's talking about being all-in on this game), and considering the festering situation with Mike Peterson, there is plenty going on that could distract the team.
5. Play Best in the Big Game-This game can define the season. If the Jaguars win, their playoff hopes are alive and they would be the first to beat the Titans this year. If the Jaguars lose, it will be nearly impossible for them to make the post-season. Last year, the Jaguars responded down the stretch. Can they do it again this year?
