5 Critical Lessons Learned from Week 1 of 49ers Training Camp

The San Francisco 49ers have their work cut out for them as the team concluded its first week of training camp ahead of the 2015 NFL season.

Talk of all that has transpired in Santa Clara has given way to how head coach Jim Tomsula and Co. can revamp and reenergize this franchise. While the notable shake-ups—players, coaches and personnel—have cast doubt, the 49ers are still in a good position to make headway over the course of the year.

And it all starts in camp.

The opening week revealed a number of valuable takeaways from San Francisco's efforts. Tomsula is not going to be former head coach Jim Harbaugh. His way of doing things will be different. And the results, for better or for worse, shall be revealed in due time.

New arrivals are making an impact. Rookies, such as talented wideout DeAndrew White, provide a boost to the incumbent group of veterans. 

There are also developmental factors, injuries and the seemingly ever-present problems that exist with the turf at Levi's Stadium.

San Francisco still has a good amount of time left on its camp schedule, but here are some crucial first-week notes that prompt further examination.

Turf Woes Abound

Levi's Stadium's sod continues to be an ongoing problem.

Loose sod and unsure footing was a major theme surrounding the debut of Levi's Stadium a year ago.

It should have stayed there.

But the turf continues to be a problem during camp. The field resembled the poor condition it once displayed around this time a year ago, and it was enough to convince head coach Jim Tomsula it was a problem.

“We’ll reserve our right to make decisions as we need to,” Tomsula said via Matt Maiocco of CSN Bay Area. “They’re going to roll it and work it all night, but we’re not going to come out if it’s not good.

"We’re not going to put them at risk."

The 49ers have adjacent practice facilities outside of the stadium. Those will work for continued camp practices if necessary. But what about the preseason? The regular season?

A poor playing surface may not seem like a major problem, but consider the injury potential. Take, for example, linebacker NaVorro Bowman and his comeback from the torn ACL and MCL from two seasons ago.

Could there be a critical injury for one of the 49ers' receiving targets? Wideouts, running backs and tight ends stop, pivot and change directions all too frequently to suggest the field won't be a problem.

The Cornerback Position Battle Is Fierce

B/R's Matt Miller described in the above video that one of the critical competitions to watch this training camp will be at cornerback.

It should be. And it has been.

San Francisco enters the season after losing corners Chris Culliver and Perrish Cox to free agency. The two combined for nine interceptions last year, and the secondary will look to replace their production with a new-look cast of players vying for a handful of spots.

Cornerback Tramaine Brock already figures to be the No. 1 starter despite having played in just three games last season. But who plays alongside him is up for grabs.

Veteran corner Shareece Wright is one name who could get the call here. Wright struggled over his last two seasons with the San Diego Chargers, but he has made an impact in San Francisco thus far.

Wright picked off quarterback Colin Kaepernick after an all-out blitz on Wednesday and returned the interception for a touchdown.

Taylor Price of 49ers.com described the play:

"

The added pressure was noticeable on Tuesday when an all-out blitz in a move-the-ball period led Kaepernick to force a pass to Quinton Patton, which was intercepted and returned for a 20-yard touchdown by Shareece Wright.

"

The 49ers also have a young cast of developing corners who could turn heads this training camp, especially after the release of Chris Cook on Wednesday.

Defensive backs Dontae Johnson and Keith Reaser may lack experience, but the combination does have talent. 

Perhaps one of these two will emerge as a starter alongside Brock.

The D-Line Will Drive the Defense

San Francisco's defensive line is deep, even after the retirement of defensive end Justin Smith.

Defensive coordinator Eric Mangini's defense may be a little more aggressive than it was under Vic Fangio, but the D-line will still be the inherent strength of this unit.

As stated by B/R's Matt Miller above, a primary training camp battle will be between defensive ends Tank Carradine and Arik Armstead. Miller concludes Carradine will likely be the Week 1 starter with the rookie Armstead being worked into a rotation of sorts.

Carradine has shown positive signs in camp so far per Ryan Sakamoto of NinerFans.com.

Carradine and the D-line will be responsible for opening up lanes for San Francisco's pass-rushers to pressure the quarterback. This unit will also be required to limit the running game. The 49ers allowed 1,612 rushing yards last year, which was seventh in the league.

Healthy returns of linemen Glenn Dorsey and Ian Williams will reinforce this group. The addition of veteran defensive tackle Darnell Dockett also helps in various pass-rushing situations.

But, overall, if this group can maintain its prowess through camp and into the regular season, the 49ers defense should remain a primary strength.

Will Colin Kaepernick Return to 2012 Form?

While the defense was solid in 2014, San Francisco's offense ranked No. 25 in the league in total points scored (306). The passing game was even worse.

The 49ers posted a mere 3,063 yards through the air, which ranked No. 30 in the NFL. 

Perhaps some of the blame fell on former offensive coordinator Greg Roman who, according to Niners Nation writer @SocaliSteph, suffered from a "paralysis by analysis." Perhaps the former coaching regime tried to have quarterback Colin Kaepernick do too much in 2014.

Whatever the case, new offensive coordinator Geep Chryst will be charged with figuring out a way for San Francisco's offense to get on track.

New weapons like wide receiver Torrey Smith and running back Reggie Bush provide options.

But as the B/R video suggests above, the best solution may be to simplify the offense. This isn't to state the 49ers' offensive approach will be overly simple. Rather, it should focus on the strengths of Kaepernick and allow him to play the style of game that made him noteworthy in 2012.

Still, that doesn't mean Kaepernick is without room to improve.

Chryst stated, via Matt Maiocco of CSN Bay Area, he wants Kaepernick to focus more on his targets' body language over the course of camp.

"What we’re talking about more is reading the body language of some of these new receivers," Chryst said.

The offense has also been working on better communication at the line per Taylor Price of 49ers.com.

San Francisco was tied for most delay-of-game penalties, with eight accepted last season.

Tomsula Is Changing the Culture

Head coach Jim Tomsula (left) and general manager Trent Baalke (right) are "on the exact same wavelength."

The departure of former head coach Jim Harbaugh might have been a sour spot in recent 49ers history. His rift with the front office created an unneeded black eye for the organization that may linger for some time.

But head coach Jim Tomsula is trying to steer clear of all those distractions and point his team in a positive direction.

Part of that solution is to rectify offensive problems.

"Fix it," is a portion of practices that are held at the end of the day per Taylor Price of 49ers.com. Price writes:

"

A noticeable change of San Francisco's camp practices under Jim Tomsula is the final practice period dubbed, "Fix it."

[Colin] Kaepernick said plays that weren't executed properly will be reviewed at the end of the session. Both sides of the ball run plays at a walk-through pace, allowing the offense to better understand the errors that were made.

"

Another example is how Tomsula is trying to focus more on simplifying the offense and showcasing quarterback Colin Kaepernick's strengths—an aspect seen in the B/R video on the previous slide.

Tomsula has also stated he is confident in San Francisco's perceived greatest weakness: the offensive line, and general manager Trent Baalke is in agreement with his head coach.

“I think we’re both on the exact same wavelength with it,” Baalke said via Matt Maiocco of CSN Bay Area. “We like this group.”

Tomsula may be best off simply getting the entire offense, and team for that matter, pointed into a direction where it can maximize its strengths.

Instead of getting overly creative and complex with scheme, this approach may better suit a first-year head coach and a large cast of first-year starters like running back Carlos Hyde, defensive end Tank Carradine and, possibly, some members of the O-line like linemen Brandon Thomas and/or Trenton Brown.

Week 1 of training camp tends to iron out the kinks. The 49ers still have many.

But if Tomsula can continue to showcase the positive aspects of his team while improving the negatives, San Francisco should be in much better shape than many have anticipated entering the season.
