Jaguars have several key players entering final year of their contract

JACKSONVILLE, Fla. -- The 2015 season is almost upon us. Training camps begin soon, the Hall of Fame game is Aug. 9, the preseason begins Aug. 13, and the first regular-season game is Sept. 10.

To get you ready for the Jacksonville Jaguars' season, I'll have a list of 15 things to know, ponder and file away. The series will continue each weekday until training camp begins July 31

Call it 15 for '15.

Today: Impending free agents

The Jaguars have 10 players whose contracts expire after the 2015 season and will become unrestricted free agents. Two of them are players that may not make it to the regular season -- running back Bernard Pierce and offensive tackle Sam Young -- but the remaining eight should be key players in 2015.

Here's a quick look at each player:

QB Chad Henne: He will be the top backup to starter Blake Bortles and it's a role in which he can thrive. He's a veteran who understands what it takes to be a starting quarterback in the NFL and is a good influence on Bortles. The way he handled his benching last season really impressed his teammates and the coaching staff. Bortles likes and respects him, too. I can see him re-signing to remain Bortles backup for those reasons.

WR Tandon Doss: With the release of Ace Sanders, Doss is the favorite to win the punt returner job. He led the NFL in punt return average in 2013 before an ankle injury cost him the entire 2014 season. He's a physical receiver, too, and that helps his chances of making the team. The only problem would be if fifth-round pick Rashad Greene looks good as a returner in camp, which could put Doss' spot on the roster in jeopardy.

TE Marcedes Lewis: The franchise's all-time leader in receptions by a tight end restructured the final year of his contract, dropping his cap number from $8.2 million to $3.85 million. The addition of Julius Thomas means that Lewis becomes the No. 2 tight end but he still should get a decent amount of work because offensive coordinator Greg Olson likes two tight end formations. If he has a good season, which includes staying healthy (he has missed 13 games over the past two seasons), then there's a chance he could return in 2016 -- but only at a reduced salary. Most likely, though, this is his final season in Jacksonville.

TE Clay Harbor: He had a good start to the 2014 season, catching 25 passes in a six-game stretch after he missed the first three games with a calf injury. But he had just one catch in the final seven games. He will get work in multiple tight end sets, though he's more of a flex tight end than an inline blocking tight end. It's hard to know where he fits in until we see how much he'll be used.

C/G Stefen Wisniewski: The former Oakland Raider signed a one-year prove-it deal and will compete with Luke Bowanko to be the starting center. He's another player that must prove he can stay healthy. Though he has missed just three games in four seasons he has battled shoulder injuries throughout his career. If he remains healthy and plays well the Jaguars would likely try to sign him to a multi-year deal.

DE Andre Branch: The Jaguars' 2012 second-round draft pick enters the final season of his rookie contract with just 10 sacks. He had 6.0 in 2013 but missed seven games with a groin injury in 2014. He has a chance to prove himself worthy of an extension this season because of the loss of first-round pick Dante Fowler. A monster season doesn't seem likely so if he comes back he would have to be OK with a contract likely not much more than the veteran minimum.

K Josh Scobee: The leading scorer in Jaguars history is scheduled to earn $3.425 million in 2015. It's safe to say he won't be able to demand anything near that kind of salary if he were to return. He's still one of the more accurate kickers in the league and has been very good from 50-plus yards. The Jaguars signed Jason Myers to a three-year deal earlier this year so they have insurance if Scobee were to struggle in camp.

P Bryan Anger: Coach Gus Bradley raved about how well Anger was punting during OTAs and minicamp. Teams generally don't invest a lot of money in a punter but if he has a good season there will be interest in him returning.
