Sunday Roundup: T. Jackson, Osweiler, Jags

The brief post-Super Bowl lull has set in on the NFL world, but the first day of free agency is right around the corner, and you can bet that there will soon be reports concerning contract extensions, franchise tags, etc. As we await that deluge, let’s take a look at some news and notes from around the league:

• Seahawks backup quarterback Tarvaris Jackson is expected to test the free agent market this year, according to Jessamyn McIntyre of 710 ESPN Seattle (via Twitter). McIntyre reports that there was a strong market for Jackson’s services last season before he ultimately decided to re-up with Seattle.
• Mike Florio of Pro Football Talk wonders what it will take for the Broncos to retain Brock Osweiler, especially since there are likely to be a number of teams like the Texans, Jets, and Rams potentially willing to bid against Denver for his services. We learned yesterday that a contract with an AAV of around $9MM would probably not be enough to prevent Osweiler from testing the free agent market, and Florio appears to concur with that sentiment.
• Kevin Acee of The San Diego Times-Tribune explores potential stadium sites in San Diego that the Chargers might consider, concluding that the Mission Valley site, although less exciting, is more likely than the East Village option.
• Although there have been rumors that the Jaguars will consider adding an offensive tackle this offseason, Ryan O’Halloran of The Florida Times-Union would be surprised if that happened. O’Halloran notes that the Jaguars’ two starting tackles, Luke Joeckel and Jermey Parnell, currently account for the third and fourth highest cap charges on the roster, respectively, and he adds that no starting-caliber free agent tackle would sign with Jacksonville at this point.
• Joe Person of The Charlotte Observer looks at the biggest issues facing the Panthers this offseason. He believes that Carolina will ultimately put the franchise tag on Josh Norman and should ask defensive end Charles Johnson to rework his current deal.
• Although he may be a bit biased, former NFL GM and well-respected football mind Bill Polian believes the Lions made the right decision in retaining Jim Caldwell, per Kyle Meinke of MLive.com. Polian points to the team’s drastic improvement in the second half of the 2015 season and the players’ support of Caldwell as indicators that Caldwell is the right man for the job.
