MIAMI — When Broncos quarterback Drew Lock finished his duties at the team’s facility Dec. 30, he told himself and his family he was going to take an entire month off. Take a trip. Sleep in. Not touch a football.

He went 2-for-3.

“Being able to go on vacation with (girlfriend Natalie) and go on vacation with my family and just take a deep breath and not have to go to bed thinking, ‘OK, what do I have to get done tomorrow?’ and wake up whenever I wanted to, it was (enjoyable),” Lock said Friday in an interview with The Denver Post after an autograph session at the Miami Beach Convention Center.

But …

“I’ve already thrown three times and started to work out,” Lock said with a laugh. “You think you want to take a break, but then it starts kicking in — ‘OK, I have to start moving around again. I have to get back to doing something.’”

Lock did a lot of something once he was named the Broncos’ starter, going 4-1 with seven touchdowns, three interceptions and an 89.7 rating, fueling optimism inside and outside of the organization entering 2020.

Lock will split his offseason between Kansas City and Denver, and when he’s in Colorado, he intends to connect with Peyton Manning to talk about, well, everything.

“I pretty much see him as a mentor,” Lock said. “He’s a guy that’s invested so much time in football and loves the game of football so much, what better brain to pick? When did he start throwing in the offseason? How many weights did he lift? What days did he lift? How did he get the guys together (to throw)? Where did he go?

“Everything, really. And he’ll have the answers, too.”

When Manning debuted for Indianapolis in 1999, Tom Moore was his offensive coordinator and remained in that role (or on the staff) until 2010. Continuity reigned for the Colts as they moved from coaches Jim Mora to Tony Dungy to Jim Caldwell.

Lock won’t be as fortunate. The Broncos fired offensive coordinator Rich Scangarello and quarterbacks coach T.C. McCartney, replacing them with Pat Shurmur and Mike Shula, respectively.

“It’s always sad when people get let go, especially because of the relationships you build,” Lock said. “I was extremely close with T.C. throughout the year and I was able to see how Coach Scans coached. How they treated me, whenever I needed help with something, they were always there for me. That’s the hardest part about seeing those guys go. But at the same time, we’re really excited about who’s coming in and we have to build on what we did at the end of last year and carry it into this year.”

Shurmur’s offense will be Lock’s fourth in as many years dating back to Missouri. Lock stopped by the Broncos’ facility earlier this week and had a quick meet-and-greet with Shurmur. League rules prohibit any football-related sessions until the start of the offseason program this spring.

Does having to learn so many new offenses actually aid in the transition?

“Without a doubt,” Lock said. “I haven’t been able to talk football with Coach Shurmur yet, but the bottom line is, he said he’s going to make it as easy as possible for us to learn it, pick it up, play fast and be confident in what we’re doing. As far as being able to transition to another offense, I’ll be ready to do it.”

Before last year’s draft, Lock took a pre-draft visit to the New York Giants’ facility and met with Shurmur (coach) and Shula (offensive coordinator/quarterbacks coach).

“I was happy that (the new coaches were) at least somebody I knew and had talked to before and had good feelings about,” Lock said. “I had lunch with Coach Shurmur in New York and had meetings with Coach Shula so I feel like I have a good idea about who they are, but obviously I’m going to get to know them a lot better now. I’m excited to work with both of them.”

Late in the regular season, Scangarello said he and McCartney were preparing an offseason to-do list for Lock. Shurmur will get to that, too, but Lock said he has already prioritized a focus point.

“Besides throwing and getting into the playbook, once I’m allowed to, is focusing on my speed,” said Lock, who gained 72 yards on 18 carries last year, but also extended numerous plays. “I feel one of the biggest things in my game is being able to get out of the pocket and running around and I want to utilize that this year. Speed, quickness, agility — all that kind of stuff — will be big for me.”
