Vinatieri signs, Smith is on the shelf. (NFL)

There are a number of interesting story lines in the NFL as far as the off-season and next season are concerned, and I'm going to take you through several of them.

Adam Vinatieri signs. The long-time kicker, and current old fart of the league, has signed a one-year extension to stay in Indianapolis and keep whacking field goals for the Colts. Personally, after watching him kick in the divisional game against the Chiefs, I believe he should probably retire. He's been a hell of a player, one of the best kickers ever, but he's no spring chicken anymore.

Antonio Brown to the 49ers? Brown wants out of Pittsburgh (hard to blame him), and has said several times in the past couple of weeks that he really wants to join San Francisco. As a 49er fan, I love this idea. Even the greatest receiver of all time, Jerry Rice, has supported Brown in this. I'm not sure what the Niner brass is waiting for. GO GET HIM!

Alex Smith will probably miss all of next season. The Redskins QB looks to be heading for the shelf due to complications with the nasty leg injury he suffered this past season. As much as I like Smith, and even though he said he's going to come back at some point, I think he should contemplate the future a little more. That leg will never be normal again. He made a lot of money over the years, and should leave playing game, perhaps becoming a coach or coordinator.

Flacco to the Jags? This might seem like complete hogwash to some, but there is reason to believe this could become a reality. Flacco is done with the Ravens, and Jacksonville needs a franchise QB for the upcoming season (because Blake Bortles SUCKS) and are said to be interested in Flacco. Even the boys on PTI have said this is probably the most likely scenario for the Jags. Flacco is getting old, but he's certainly better than anything the Jags have had in recent years.
