Team Needs: AFC South

One of the NFL's weakest divisions is rife with teams in need of substantial reinforcements. Even the reigning division champions, the Indianapolis Colts, are perilously thin at a number of vital positions. 

Let's take a look at the players teams in the AFC South may be targeting in free agency and the draft.

Houston Texans

Positions of need: Quarterback, defensive back, defensive tackle

The Texans came within a win of the playoffs in 2014 largely due to an MVP-caliber season from J.J. Watt. If not for Watt's otherworldly play, the team may have contended for the first overall pick for a second straight year. The Texans' quarterback play was disastrous, their secondary was a mess and first-overall pick Jadeveon Clowney contributed next to nothing. 

Watt can't keep propping up this team on his own. The Texans must retain their key impending free agents and then add talent on both sides of the ball in order to return to contender status. Top priority must be acquiring a starting quarterback. Ryan Fitzpatrick won't be back and Ryan Mallett is an impending free agent, leaving only 2014 fourth-round pick Tom Savage as anything resembling a viable starting option. Jameis Winston and Marcus Mariota will be out of reach in the draft and after them, pickings are slim.

Potential free-agent targets: Re-signing Mallett on a team-friendly deal should be a priority, but the Texans should look to add talent at quarterback regardless of whether Mallett returns. Mark Sanchez and Brian Hoyer could be fits for Bill O'Brien's scheme. 

On defense, re-signing Kareem Jackson would be ideal, but only if the price is right. Adding a cornerback like Byron Maxwell or Brandon Flowers, or drafting one like Trae Waynes, to man the other side of the field is another appealing option. 

Indianapolis Colts

Positions of need: Offensive line, edge rusher, running back

The Colts' biggest needs are the same ones they've largely failed to address since drafting Andrew Luck in 2011: offensive line, pass rusher and running back. 

General manager Ryan Grigson has hinted the team will spend aggressively in free agency and the market won't lack talented edge rushers or tailbacks. Offensive line is another matter, so the team may be forced to look to the draft to fill its holes in front of Luck. 

Potential freeagent targets: Bjoern Werner looks like a bust and Robert Mathis may never return to form after a devastating Achilles' tear, so the Colts could stand to add two edge rushers. Greg Hardy, Brian Orakpo, Pernell McPhee, Brandon Graham and Derrick Morgan are some of the names Grigson may have on speed dial. 

With Trent Richardson likely to be released, the Colts could look to add a more reliable running back. Frank Gore stands out as a good scheme fit, but he isn't a long-term answer at the position. If Adrian Peterson becomes available, expect the Colts to pounce.

Jacksonville Jaguars

Positions of need: Offensive line, defensive line, tight end

The bad news? The Jaguars have a plethora of holes to fill on both sides of the ball. The good? They have plenty of salary-cap space to do it. 

Look for the Jaguars to come out swinging in free agency and attempt to land at least one of the biggest names available. Then look for them to remain aggressive and pick off second-tier bargains. Seven total wins over the past two seasons won't cut it. It's time for David Caldwell and Gus Bradley to take this team to playoff contention or make way for someone who can.

Potential free-agent targets: If Ndamukong Suh hits the open market, look for the Jaguars to be one of the few teams willing to write a blank check to acquire his services. 

Julius Thomas and Randall Cobb are two big-name offensive players the Jaguars could target. Blake Bortles needs weapons he can rely on. 

Tennessee Titans

Positions of need: Edge rusher, safety, offensive line

The Titans converted to a 3-4 base defense in 2014 and, like many teams that make the switch, the initial results weren't promising. The Titans lack viable 3-4 talents throughout their defense, but their most glaring holes are at edge rusher. If Derrick Morgan leaves in free agency, the Titans will have essentially no NFL-caliber edge rushers on the roster. 

The Titans have invested lots of money and multiple first-round draft picks along the offensive line, yet have a bottom-tier unit. Taylor Lewan and Chance Warmack are entrenched as starters, but the Titans must find a new right tackle and consider moving on from the hilariously overpaid Andy Levitre at guard. 

Like most teams in the AFC South, the Titans have plenty of salary-cap space to fix their problems in free agency. 

Potential free agent targets: With Dick LeBeau now running the Titans' defense, it's almost too obvious that the team will target Jason Worilds to boost its pass rush. A second edge rusher, perhaps Brian Orakpo, should be item No. 2 on the Titans' shopping list. 

Signing Bryan Bulaga would immediately shore up the offensive line, but Doug Free may be a more realistic target. Don't count out the possibility of the Titans spending big on a guard or center, too, despite the lingering pain of whiffing on Levitre a few years ago.

The free-agent safety class is woeful, so the Titans may be forced to address their issues there in the draft.
