The Tennessee Titans have been as busy as you could have possibly expected this offseason, and they might not be finished just yet.
There are still some missing pieces for this team that the Titans need to explore getting if they really want to give themselves a chance to take the AFC by surprise.
Here are some missing pieces that still need to be added for the Titans to cap off what has been a really productive offseason.
John Abraham may be on the back end of his career, but he's still the premiere pass-rusher that this Titans defense has been lacking for years.
The Titans didn't address the defensive line until the middle part of the draft, which came as somewhat of a surprise to many.
Outside of Kamerion Wimbley and Derrick Morgan, there's really no moderate pass-rusher for the Titans. Even Morgan still has a lot to prove.
Adding another accomplished pass-rusher like Abraham would really round out what has been a solid offseason in upgrading this Titans defense.
According to Adam Schefter of ESPN, Abraham and the Titans are in talks to make a deal happen possibly as early as this week.
Don't be surprised if the Titans make yet another big offseason move by getting Abraham and solidifying their pass rush.
Health concerns have dropped Dallas Clark's value over the years, but he made it through all 16 games last season for the Buccaneers.
The Titans still need a solid pass-catching tight end after losing Jared Cook.
They may have added Delanie Walker, but he is more of a blocking tight end, and a good one at that.
After Walker, the Titans have Craig Stevens and Taylor Thompson. In other words, the position is pretty thin when it comes to having a reliable receiver.
The Titans could get Clark for moderately cheap and get a great veteran to help out Jake Locker.
If Clark doesn't decide to hang up the cleats to what has been a great career, then the Titans should try to get one more year out of him.
The Titans could use a little more depth at middle linebacker behind Colin McCarthy, who battled injuries throughout his second NFL season.
We still don't know if McCarthy's health is going to be an ongoing problem, and the Titans have to prepare for the worst scenario.
McCarthy seems to have a bright future if he stays healthy, but Tim Shaw is not a long-term solution as his backup. He's primarily just a solid special teams contributor at best.
Maybe adding a cheap veteran like former Jaguar Daryl Smith in free agency is an option.
Adding an undrafted free agent to get some young depth behind McCarthy would also be a wise choice for the Titans.
The Titans don't necessarily have a glaring need for starters at defensive tackle with guys like Jurrell Casey and Sammie Lee Hill, but they could always use a rotational guy to add for depth.
A few injuries to this unit could really put the Titans in a tough spot, so getting another defensive tackle is something the Titans should look into.
The Titans drafted Antonio Johnson back in 2007, and he has since played for the Colts.
Johnson would be a good fit on this roster for a really cheap price and protect the Titans if injuries plague the unit.
