After one of the biggest nosedives in NFL history, the Houston Texans should rebound from their 2-14 embarrassment and earn respectability, but not a division title.

That will once again go to the Indianapolis Colts, according to a survey The Sports Xchange's football staff, which expects Jacksonville and Tennessee to battle it out for the basement spot that Houston will vacate this year.

Here is a closer look at AFC South teams as training camp begins (teams listed alphabetically):

CAMP PREVIEW: Houston Texans

--TSX Predicts: 2nd in AFC South

--2013: 2-14, 4th in AFC South

--Training Camp Dates (rookies, vets report): Houston Methodist Training Center, Houston, Tex., 7/21, 7/25

--2014 Opponents Win Percentage in 2013: Division .458 (T19/32); non-division .431 (31/32); overall .441 (30/32).

--Primetime Games: 2 (1 Thursday, 1 Monday Night)

--STRENGTH: The front seven with four former first-round picks -- end J.J. Watt, inside linebacker Brian Cushing, outside linebacker Jadeveon Clowney and outside linebacker Whitney Mercilus -- and a former second-round pick, inside linebacker Brooks Reed.

--WEAKNESS: Defensive back. The Texans' defense ranked third worst out of 32 teams last season in average passing yards allowed per game (195.2). They went from bad to worse with the mid-season departure of veteran Ed Reed and rarely played as one. The offseason loss of veteran Danieal Manning doesn't help and leaves the Texans relying on a list of little-known names to tighten an erratic secondary in defensive coordinator Romeo Crennel's first year with the team.

Veteran safeties Kendrick Lewis and Chris Clemons were added via free agency, while Shiloh Keo and D.J. Swearinger will again compete for starting spots. At cornerback, returning players Johnathan Joseph and Kareem Jackson will lead a young, inexperienced group.

CAMP PREVIEW: Indianapolis Colts

--TSX Predicts: 1st in AFC South

--2013: 11-5, 1st in AFC South

--Training Camp Dates (rookies, vets report): Anderson University, Anderson, Ind., 7/23, 7/23

--2014 Opponents Win Percentage in 2013: Division .271 (32/32); non-division .525 (T10/32); overall .430 (32/32).

--Primetime Games: 5 (1 Thursday, 2 Sunday Night, 2 Monday Night)

--STRENGTH: Quarterback Andrew Luck. The Colts will only go as far as the team's third-year signal-caller will take them. Luck has guided Indy to consecutive post-season appearances and a memorable come-from-behind win over Kansas City in a wild-card game last year.

--WEAKNESS: Center. A dozen plays. That's all the game experience second-year center Khaled Holmes had last season as a rookie with Indianapolis. Now with the decision to release two-year starter Samson Satele and not re-sign center/guard Mike McGlynn, Holmes will go into the 2014 season as the team's top option at the center position.

The depth includes a pair of undrafted rookies -- former Florida center Jonathan Harrison and a local product in ex-Indiana State center FN Lutz III. Guard Hugh Thornton could move in to play the position if needed and another guard, Donald Thomas (who is recovering from injuries suffered early last season), has limited experience at center.

CAMP PREVIEW: Jacksonville Jaguars

--TSX Predicts: 4th in AFC South

--2013: 4-12, 3rd in AFC South

--Training Camp Dates (rookies, vets report): Florida Blue Health & Wellness Practice Fields, Jacksonville, Fla., 7/21, 7/24

--2014 Opponents Win Percentage in 2013: Division .417 (T25/32); non-division .475 (T22/32); overall .453 (29/32).

--Primetime Games: 1 (1 Thursday)

--STRENGTH: Defensive line. The last two years, the Jaguars have been at or near the bottom of the league in sacks or putting any pressure on opposing quarterbacks. That doesn't appear to be the case anymore. The free-agent signing of players like Chris Clemons, Ziggy Hood and Red Bryant brings instant credibility to this unit.

Andre Branch had a banner second-half season a year ago and if that continues, he could produce double-digit sack totals. For the Jaguars to be able to cut veteran defensive end Jason Babin shows that they have confidence in the remaining group of players along the line.

--WEAKNESS: Interior offensive line. The current starters at center and right guard were backup players a year ago with a combined five starts at different positions. Center Mike Brewster started three games at left guard, while current right guard starter Jacques McClendon was a two-game starter at left guard. So neither has started a game at his current position.

The backup players are a pair of mid-to-late-round draft picks last month. Brandon Linder was taken in the third round (No. 93 overall) to challenge McClendon at the right guard spot while Luke Bowanko was a sixth-round selection (No. 205 overall) who was the starting center at the University of Virginia. They may be starters in the future, but neither look ready to make a legitimate run at a starting job in 2014.

CAMP PREVIEW: Tennessee Titans

--TSX Predicts: 3rd in AFC South

--2013: 7-9, 2nd in AFC South

--Training Camp Dates (rookies, vets report): Saint Thomas Sports Park, Nashville, Tenn., 7/25, 7/25

--2014 Opponents Win Percentage in 2013: Division .354 (31/32); non-division .488 (T18/32); overall .438 (31/32).

--Primetime Games: 2 (1 Thursday, 1 Monday Night)

--STRENGTH: Offensive Line. The Titans have gone to great lengths to rebuild an offensive line eroded over the past several years, and this unit -- on paper at least -- would appear to be the strength of the team.

The Titans signed left guard Andy Levitre last year as a free agent and drafted right guard Chance Warmack and center Brian Schwenke. This year they added free-agent right tackle Michael Oher and took future left tackle Taylor Lewan in the first round as an eventual successor to stalwart Michael Roos, who is entering the final year of his contract.

--WEAKNESS: Wide receiver. There is talent at the top of the depth chart with shifty Kendall Wright in the slot, and steady Nate Washington on the outside. Justin Hunter also has big-play potential. But after that, there are just unproven names.

Michael Preston, a former practice-squad player, has 10 career catches. Marc Mariani, a former Pro-Bowl pick as a return man, has just five catches and has spent the past two seasons on injured reserve. The Titans added Brian Robiskie, who failed to produce elsewhere. So quarterback Jake Locker hopes to find a couple more reliable receivers to help him in Ken Whisenhunt's new offensive system.
