The Tennessee Titans are coming off an embarrassing overtime loss last week to the previously winless New York Jets.The Jacksonville Jaguars have lost 19 straight games, dating back to last year. They were trending for all the wrong reasons earlier this week after a video of coach Urban Meyer, who is married, appeared to show him acting in an inappropriate fashion with a woman at his restaurant in Columbus, Ohio.Little wonder that both teams can’t wait to get on the field Sunday in Jacksonville and try to create some good news in their AFC South matchup.Tennessee (2-2) hasn’t exactly lived up to huge preseason expectations, aside from NFL rushing leader Derrick Henry. His 510 yards are 61 more than the Jaguars have as a team, and he has traditionally enjoyed huge games against the divisional rival.And it’s no secret that the Titans need a lot from Henry. They listed 21 players — more than 40 percent of their active roster on game day — on their injury report Wednesday. Eight didn’t practice, including ballyhooed offseason acquisition Julio Jones (hamstring).What’s more, their offensive line is having trouble keeping quarterback Ryan Tannehill upright. Tannehill absorbed seven sacks against the Jets and has been sacked a league-high 17 times in four games.”I don’t think you can pin it on any one group or any one person,” Tannehill said. “I think everyone has played a part and as a group, we just have to clean it up. We’ve had opportunities and we’re this far away for a lot of reasons on different plays.”Tennessee’s defense remains a concern, too. After spending more than $100 million for free agents such as Bud Dupree, Denico Autry and Janoris “Jackrabbit” Jenkins, the Titans are allowing 27.8 ppg — 26th in the NFL. Jenkins has allowed opponents to compile a 103.7 quarterback rating on balls thrown his way, which would be a career worst.One senses Jacksonville (0-4) would love to have those problems.
