Position battle: Tennessee lost Jonnu Smith this offseason, seeing him sign a big deal with the Patriots. This leaves a hole at tight end for the Titans. Anthony Firkser is the odds on favorite to start, but he could be pushed by veteran Geoff Swaim, who might be a little more complete tight end. Firkser will need to show he can help as a blocker in addition to being a good pass catcher if he hopes to optimize his playing time this year.

Injury watch: The Titans made a big splash this offseason, acquiring Julio Jones to start opposite A.J. Brown. Jones needs to be on the field to help his new team, though. He was limited to nine games last year and has missed games each of the past two seasons. Jones has been nicked up with various injuries in recent seasons. He is 32 years old, so you have to wonder a little if he can hold up after the last few seasons.

Colts

The Colts had a good season last year, finishing 11-5, but will look to get even better this year. The big thing to watch this camp is quarterback Carson Wentz. He was brought in to take over as the starter for the Colts. If he can get back to playing at a high level, the Colts could take their offenses to new heights this year. Wentz and the offense will get going at Grand Park in Westfield, Ind.

Position battle: Receiver Parris Campbell has played nine games in two seasons. He has a lot of talent but won’t be handed anything. He will need to earn the No. 3 receiver job. He has Zach Pascal to compete with for that job. Pascal has 40-plus receptions two straight seasons. He has played pretty well with his chances. Campbell will have a battle on his hands for the No. 3 receiver spot in Indy.

Injury watch: Marlon Mack played a game last year, tearing his Achilles in Week 1. Mack was expected to have a pretty big role with the team after hitting the 1,000-yard mark the previous season. If he can get back to health this year, he could challenge for the top backup job for the Colts. He will need to prove he is healthy, though. Mack gives the Colts some good insurance behind Jonathan Taylor.

Jaguars

The Jaguars have a lot of new going on this year. There is a new coach, Urban Meyer, and a new franchise quarterback, Trevor Lawrence. This duo will look to take the franchise in a new direction. Both of these guys should be the main focus of training camp. A lot is riding on each of them to get this franchise headed in the right direction. Meyer and Lawrence will train at the Dream Finders Homes Practice Complex at TIAA Bank Field in Jacksonville, Fla.

Position battle: We aren’t sure if this is a position battle because both backs are going to play, but it will be interesting to see how the playing time shakes out for James Robinson and rookie Travis Etienne. Robinson was a huge surprise last year and played at a very high level. Etienne is a super talented back, though, with a high ceiling. Both these guys should see plenty of touches this year, but it will be interesting to see how they are used. We should get a better idea starting in training camp and preseason action.

Injury watch: He isn’t coming off an injury but he has not played in several seasons and is trying to learn a new position. There should be a lot of eyes on Tim Tebow this training camp. He has a lot working against him to make the team, but you never can seem to count him out. Tebow will try to make the team as a tight end, a position that is really thin for the Jaguars right now. Plus, the Jaguars could use him as a gadget player, similar to Taysom Hill. This will be something to keep an eye on this training camp.

Texans

Houston was a bit of a mess last year and could be even more of a mess this year because of the uncertainty surrounding their franchise quarterback, Deshaun Watson. The Texans also traded or released some player this offseason that were big-time contributors to the team in the past. There is a lot of things to be decided this camp, which should make things interesting. Houston holds training camp at the Houston Methodist Training Center in Houston, Texas.

Position battle: The Texans have quite a crowded backfield. David Johnson played alright in his first season as the starter last year, but the team brought in a lot of help for him. The Texans added Mark Ingram, Phillip Lindsay and Rex Burkhead. These are all proven backs that have played well in the past. It will be intriguing to see how they are all used this year in Houston. Will the Texans rotate backs or continue to have Johnson as the guy getting the bulk of the carries? This is certainly a fantasy situation to watch.

Injury watch: Deshaun Watson isn’t injured but has all sorts of issues surrounding him this training camp. He is in legal trouble and also has asked for a trade. Watson is kind of in limbo right now. We might not get a much better understanding in training camp but hopefully get a few more questions answered. Watson will definitely be a player to keep an eye on in Houston’s camp, if he is even in camp.
