The NFL’s AFC South, which had previously been one of the weakest divisions in football, sent two teams to the playoffs last season in the Jaguars and Titans. Jacksonville was less than 15 minutes away from making their first Super Bowl appearance before falling to the Patriots.

The other two teams in the division are expecting star quarterbacks to return from injury. Andrew Luck missed the entire 2017 season for the Colts due to a shoulder injury while Deshaun Watson tore his ACL in practice in early November for the Texans.

According to CBS Sports, Las Vegas lists the Jaguars at -140 and Texans as -135 to make the playoffs (meaning that much has to be wagered to win $100).

The Titans are listed at +165 and Colts are at +325 (meaning that much will be won if $100 is wagered).

Here are the key additions and losses in team personnel from each AFC South team in the offseason.

Houston Texans

  • Key additions: Tyrann Mathieu, S (signed), Senio Kelemete, G (signed), Aaron Colvin, CB (signed), Zach Fulton, C (signed), Seantrel Henderson, OT (signed), Justin Reid, S (third round), Martinas Rankin, C (third round), Jordan Akins, TE (third round)
  • Key losses: C.J. Fiedorowicz, TE (retired), Tom Savage, QB (Saints), Xavier Su’a-Filo, G (Titans), Breno Giacomini, OT (Raiders), Marcus Gilchrist, S (Raiders), Brian Cushing, LB (released)

The Texans allowed opposing quarterbacks to complete 64.1 percent of their passes in 2017 for 3,799 yards and 30 touchdowns.

Those numbers were much better in 2016 when they were 61.1, 3,226, and 20 respectively.

To regain the solid passing defense they previously owned, Houston focused their offseason on improving their secondary. They jumped on former Pro Bowl safety Tyrann Mathieu once he was cut by the Cardinals. The ‘Honey Badger’ played a full 16-game season in 2017 for the first time in his five years.

They also signed cornerback Aaron Colvin away from the division rival Jaguars and used their first draft choice on safety Justin Reid out of Stanford.

Indianapolis Colts

  • Key additions: Austin Howard, OT (signed), Matt Slauson, C (signed), Ryan Grant, WR (signed), Eric Ebron, TE (signed), Denico Autry, DE (signed), Quenton Nelson, G (first round), Darius Leonard, LB (second round), Braden Smith, G (second round), Kemoko Turay, DE (second round), Tyquan Lewis, DE (second round)
  • Key losses: Johnathan Hankins, DT (released), Donte Moncrief, WR (Jaguars), Frank Gore, RB (Dolphins), Rahsaan Melvin, CB (Raiders), Barkevious Mingo, LB (Seahawks), Jon Bostic, LB (Steelers)

The Colts season rides a lot on the right arm of quarterback Andrew Luck who could also be considered a key addition after he missed all of 2017.

USA Today reports that Luck has been practicing with his wide receivers as he continues his rehab from shoulder surgery.

The team looked to improve the offensive line in order to keep the former first overall pick Luck upright. They allowed 56 sacks last season. Two of their first three picks were offensive lineman including fifth overall selection Quentin Nelson out of Notre Dame.

Jacksonville Jaguars

  • Key additions: Austin Seferian-Jenkins, TE (signed), DJ Hayden, CB (signed), Andrew Norwell, G (signed), Donte Moncrief, WR (signed), Taven Bryan, DT (first round), DJ Chark, WR (second round), Ronnie Harrison, S (third round)
  • Key losses: Allen Hurns, WR (Cowboys), Marcedes Lewis, TE (Packers), Patrick Omameh, G (Giants), Allen Robinson, WR (Bears), Aaron Colvin, CB (Texans), Paul Poslusnzy, LB (retired), Chris Ivory, RB (Bills)

The Jaguars held a 20-10 lead early in the fourth quarter against the Patriots in last season’s AFC Championship Game, but two late touchdowns by New England left the final score as 24-20.

Gone are two of Blake Bortles’ favorite targets in the past few seasons in wide receivers Allen Robinson and Allen Hurns. Taking their place on the team are former Colts speedster Donte Moncrief and second round pick DJ Chark out of LSU.

Tight ends combined to make just 43 catches for Jacksonville in 2017. Marcedes Lewis signed with the Packers after 12 seasons with the Jaguars. Austin Seferian-Jenkins was signed to bring more production to the position as he finished with 50 receptions with the Jets last season.

Tennessee Titans

  • Key additions: Bennie Logan, DT (signed), Will Compton, LB (signed), Kevin Pamphile, G (signed), Dion Lewis, RB (signed), Malcolm Butler, CB (signed), Rahsaan Evans, LB (first round), Harold Landry, LB (second round)
  • Key losses: Eric Decker, WR (unsigned), Avery Williamson, LB (Jets), DeMarco Murray, RB (released), Sylvester Williams, DT (Lions)

While the Titans’ run defense was superb in 2017, their pass defense showed holes.

On the year, they allowed 3,828 passing yards and 27 passing touchdowns.

Tennessee made a huge splash in free agency when they signed former Patriots cornerback Malcolm Butler. The former Pro Bowler becomes the team’s best player at that position. Last year’s starters, Adoree’ Jackson and Logan Ryan, did not have a single interception amongst them.

Their first two draft picks also focused on defense as they selected two linebackers: Rashaan Evans out of Alabama and Harold Landry out of Boston College.
