Join Jaguars Inside Report Senior Editor Vic Ketchman as he tackles the fans' tough questions.

Tyler from Jacksonville:
In your opinion, what do you think is the most devastating injury to a football player?

Vic: Not too many years ago, the dreaded torn anterior cruciate ligament was considered the death knell of football injuries. Not any more. ACLs are being repaired and players are reclaiming their careers. The new concern is for recurring head injuries. How many concussions are too many? When should a player who's experienced multiple concussions pull the plug? But my candidate as the new career-killer is low-back injuries. There are quite a few players in the league (Brad Johnson, Chris Weinke, etc.) who've made full recoveries from neck-fusion surgery, but it seems as though players never fully recover their flexibility and quickness after injuring their low back. Joe Montana is the exception. But for every Montana, there seems to be 10 Michael Cheevers.

Rich from Atlanta Beach, FL:
I was wondering if the players will be taking time to sign footballs, etc. and stand for a few pictures at their practices this weekend?

Vic: Players sign autographs following each practice. In addition, special autograph sessions are scheduled for this Friday and Saturday.

John from Jacksonville:
What exactly does "nine-on-seven" mean? If it's nine guys on this side of the ball and seven on that side, it doesn't seem very equitable. If so, then how can they get an accurate read of offensive and defensive performance?

Vic: "Nine on seven" is a running-game drill. It involves nine offensive players and seven defensive players. That is the number of players who are usually involved in running plays: five offensive linemen, a tight end, a fullback, a running back and the quarterback on offense, and four defensive linemen and three linebackers on defense. In short, it's seven blockers against seven defenders trying to tackle the man who has the ball.

Lee from St. Augustine, FL:
I have noticed on the roster that some players who were rookies last year are listed as having two years of experience and others are listed as having only one (this year's rookies are listed as "R"). What is the rule for whether a player in his second year is credited with one or two years of experience?

Vic: "Experience" is another way of saying "accrued seasons." For a player to be credited for an accrued season, he must have been on the 53-man roster or injured reserve list for six or more games. John Henderson satisfied the qualifications for an accrued season last year, so he is considered to be entering his second season. Danny Boyd was on the 53-man roster for only four games, therefore, he was not credited with an accrued season and is considered a first-year player this season. There is no accrued-season difference between a rookie and a first-year player. The distinction is made to let us know who is and who isn't new to the league.

Sam from Ridgecrest, CA:
When a player is declared inactive for a regular-season game, does he still suit up? And can he be activated when needed during the game?

Vic: The only deactivated player who suits up is the "third quarterback," if so declared. All other deactivated players can go get a hot dog; they won't be playing today.

John from Orlando, FL:
Being a relatively new team when compared to Tampa Bay and Miami, the Jaguars have to deal with entrenched fans of those clubs all over Florida. What are the Jags doing to cultivate support? One area to consider blitzing is the football-starved Orlando.

Vic: Fan support is built most firmly on tradition, and the only way to establish tradition is by playing games. With all due respect to marketing, I don't think it builds genuine passion and deep-seated loyalty among fans as tradition does. And you build tradition by playing big games; by winning and by losing, too. The longer the Jaguars play, the more fans they'll have. In my opinion, it's that simple.
