Training camps are winding down as we transition into the preseason schedule and more traditional game-week schedules. But before that happens, we’re taking one more look around the league to catch you up on some key training camp headlines.

In last week’s training camp tour we looked at news out of Cincinnati, Carolina, Tennessee and St. Louis. On today’s docket, we’re heading to Arizona, San Diego and Minnesota.

What Can Brown Do for the Cardinals?

The Cardinals have some tough questions to answer at wide receiver. Michael Floyd is dealing with a hand injury that will cause him to miss all of the preseason and possibly the first couple games of the regular season. Larry Fitzgerald, 31, has been held to less than 1,000 yards in each of the last three seasons.

With the starters plagued by injury and age, respectively, the door is open for 2014 third-round pick John Brown to make a significant jump in his second season.

Brown enjoyed a productive rookie season, catching 48 passes for 696 yards and five touchdowns. Those numbers faded late in the season after Carson Palmer and Drew Stanton went down with knee injuries, but were still better than expected for a rookie out of Div. II Pittsburgh State.

After two weeks of training camp, it is clear Brown is ready to build on those numbers in 2015. He has been making highlight-reel catches on the regular. He is also doing a better job escaping press coverage at the line of scrimmage, thanks in large part to the extra 10 pounds of muscle he added during the offseason.

Perhaps what stands out most is Brown’s close connection with Palmer. The two share a bond that began when Palmer was the first Cardinals players to reach out to Brown after he was drafted. That friendship grew by leaps and bounds this offseason when Brown spent a week living at Palmer’s Southern California home. Every day, the two would drive to nearby Torrey Pines HS and work on developing their chemistry.

If Brown’s training camp performance is any indication, that chemistry experiment has been a smashing success.

“[Carson] is willing to work and I’m willing to work, no matter the situation,” Brown told the team’s website. “I think that makes us pretty close.”

Team officials are fully aware Brown is on the verge of a breakout. That is one of the reasons Floyd was dangled in trade talks earlier this offseason. And even though the Cardinals never fielded a respectable offer for Floyd, the plan is still to increase Brown’s role in his second season.

End of an Era in San Diego?

Training camp has been a bitter-sweet affair for Chargers fans. On one hand, fans are excited to cheer on a team that has gone 9-7 each of the last two seasons and appears primed to do even better in 2015. On the other hand, there is a cruel reality hanging over each practice that this could be the final training camp in San Diego.

But the looming prospect of relocation is not the only thing that has Chargers fans in their feelings. There is also the team’s handling of Eric Weddle’s contract situation. Weddle is entering the final season of his contract and has said publically that if an extension is not reached by the time the regular season begins, he will cut off talks with the Chargers and leave as a free agent next offseason. The Chargers kick off the regular season on Sept. 1 against the Lions.

The acrimonious contract talks have not affected Weddle’s play during the first couple weeks of training camp. He has been all over the field, shutting down the deep passing game and undercutting passes with regularity. What has been lacking, though, is Weddle’s outgoing approach and jovial personality. It is clear he is not having fun on the field anymore, which raises concerns about whether his newfound negativity will create a toxic environment in the locker room.

At the end of San Diego’s recent Fan Fest, SDBoltReport.com reporter Jody Taylor asked Weddle to take a picture with some of the 17,000 fans who turned out to support him and the team. Weddle obliged, adding, “You never know, this might be my last one.”

The 2015 season should be one of Weddle’s best. The Chargers have a pair of shutdown corners in Brandon Flowers and Jason Verrett. They also added more talent to the secondary this offseason by signing free agents Patrick Robinson and Jimmy Wilson and drafting Craig Mager in the third round. In short, Weddle no longer has to be a one-man show.

All that remains to is to see if this contract-based negativity will affect his performance. Will he balk at playing so many snaps now that the Chargers are using “wear and tear” against him at the negotiating table? Will he be reluctant to lead a team that no longer considers him a part of its future? These questions could very well define the 2015 season for the Chargers defense and for Weddle himself.

Minnesota Remains in Flux at Right Guard

The Vikings continue to shuffle around offensive linemen in search of a solution at right guard. Brandon Fusco, who started at right guard last season, has been moved to the left side of the line. The hope is that Fusco makes life easier on LT Matt Kalil, who suffered through a disasterous 2014 season, but the switch has created a void on the right side.

Rookie T.J. Clemmings began the offseason at right guard, but has since been moved back to his natural spot at tackle. Fellow rookies Tyrus Thompson and Austin Shepherd are also focusing on the tackle position, leaving veteran Mike Harris in front of the pack at right guard. Harris, a former tackle with some positional versatility, has graded out well since making the switch.

“He’s tough. He’s not perfectly sound all the time, but he’ll fight you and he’s a big man. I’ve been pleased with him,” said head coach Mike Zimmer of Harris.

Harris has an advantage in that he is familiar with offensive coordinator Norv Turner from their time together in San Diego. Harris played tackle in San Diego, where he was relegated to a backup role because of his limited foot speed and agility, but those limitations are not as dehabilitating inside at guard.

Harris played well in the Hall of Fame game against the Steelers and bought himself more time at the position as a result. Should he fail to take advantage of the opportunity, 2014 fifth-round pick David Yankey is next in line. But at this point, it is Harris’ job to lose.
