Fall camp starts Monday. Here's the final offseason mailbag. As always, direct questions for future editions to davidmlombardi@gmail.com or follow me on Twitter.

@cnbaumgartner writes: How likely is Stanford's offense to get its third down conversion percentage back closer to what it was in 2010?

David Lombardi: Let's start with a table tracking the Cardinal's third-down conversion percentage in every season since 2010:

Stanford's Third-Down Conversion Rate Year QB Rate 2010 Andrew Luck 57.6 2011 Andrew Luck 52.6 2012 Josh Nunes 34 2012 Kevin Hogan 45 2013 Kevin Hogan 49.8 2014 Kevin Hogan 42.4

On the whole, 2014 wasn't pretty: It actually marked the worst third-down performance of Kevin Hogan's career. However, the familiar theme of immense late-season improvement rears its head here: Stanford finished with rates of over 50 percent in each of their last three games after only reaching 50 percent once before that in conference play.

So, if one believes that the Cardinal will carry over their late 2014 offensive success into 2015, there's a great chance that third-down conversion rate will return to the good side of 50 percent. That 57.6 percent clip in 2010 is ridiculous -- it led the nation by a wide margin and makes one appreciate just how dominant Andrew Luck was -- so expecting something similar to that is unrealistic. But I'm sure David Shaw would be thrilled with a 50 percent success rate, especially if Stanford can also carry over its late 2014 success in the red zone.

@PutBoobieIn writes: How many touches do you think Christian McCaffrey sees this season?

David Lombardi: Stanford fans clamored for more of the explosive freshman last year, and their wishes started to become reality late, when McCaffrey saw at least 12 touches in three of the Cardinal's final four games.

Shaw has gone out of his way to repeat that Stanford is no longer easing McCaffrey into the fold -- "now it's taking the reins off and let's go," he said -- so all indications point toward the sophomore being a versatile centerpiece of the offense.

McCaffrey is too explosive and too adaptable to be neglected this season. He averaged a remarkable 10.9 yards per touch last year, and that figure alone means that he'll receive a steady diet of the football in 2015. I expect 15-20 touches per game for McCaffrey. Even though he's added about seven pounds of muscle to better handle running in between the tackles, it's hard to know how many of those touches will come via handoffs. Remound Wright and Barry Sanders will share some of the action there, but McCaffrey is undoubtedly the Swiss Army knife of this offense, so he'll see receiving action, too. Don't forget his value as a return man -- Stanford would love to see a renaissance in special teams efficiency after a down 2014 in that category.

@JrLuvsSports writes: Hogan is a lock to be starter, I'm assuming. What's the offensive identity looking to be this season?

David Lombardi: Yes, Hogan is a lock. And Stanford's offensive identity is set in stone, too: This remains a run-first team that establishes opportunity for the play-action pass. With the tight end position back in full force (Dalton Schultz joins Austin Hooper, Eric Cotton, and Greg Taboada this season), the Cardinal appear well-equipped to feature the run-pass versatility that kept defenses guessing in the past, when opponents could never be sure if large tight ends would run block or head out for a passing pattern on any given play.

Though Stanford maintains its run-first identity, it's important to note that they won't approach the ground game in the same way as they did in the past. My last mailbag delved into this: With bruisers like Toby Gerhart, Stepfan Taylor, and Tyler Gaffney replaced by the speedier likes of McCaffrey, the Cardinal's rushing attack will focus more on emphasizing its athleticism than on bludgeoning defenses to death.

This isn't to say that the bruising mentality is dead: Shaw told me that Stanford is very excited about 220-pound freshman Cameron Scarlett. He's coming off an injury though, and it seems that it'll be at least a year before he significantly impacts the offense. Speed will be the name of the 2015 game.

@JasonAsInfinity writes: How much additional anxiety should Noor Davis' injuries cause us, given the current state of the Stanford defense?

David Lombardi: It's only natural to be worried about the Cardinal defense. They are replacing nearly the entirety of their defensive line and secondary, after all. However, if there's a position group on that side of the ball that's capable of absorbing a loss, it's Stanford's linebacker corps. An impressive collection of returning and up-and-coming talent exists there, so I don't think Davis' loss until about midseason due to a leg injury should generate extra anxiety.

It should cause frustration, though: After coming to Stanford as a touted recruit in 2012, Davis has struggled to find a spot in the regular playing rotation, and it appeared that he had finally established the inside track toward regular playing time this year. From that perspective, the timing of this setback is maddening.

That being said, the Cardinal are confident moving forward with veterans Blake Martinez, Kevin Anderson, and Peter Kalambayi as the headlining stars of the second level. They think that Kevin Palma has developed into a sturdy force on the inside, and they have seen star potential in Joey Alfieri, most recently during the spring game. Mike Tyler, Bobby Okereke, and Luke Kaumatule (who moved from the defensive line) can further fortify the position.
