Offensive Coordinator Rich Scangarello and Quarterbacks Coach T.C. McCartney will likely also help Lock with that adjustment. Scangarello, whom Lock spoke with during the quarterback's pre-draft visit, was already on the headset with the rookie quarterback during the team's first minicamp practice.

Lock said Scangarello runs a similar offense to the one the 49ers implemented during this year's Senior Bowl. Lock played for the Niners-coached squad, so he got an early look at what his future offensive coordinator could call.

"I got here, Coach 'Scang' and the boys came over and it ended up being some of the same stuff that we had already talked about," Lock said. "I wasn't sitting there in those meetings thinking I was going to actually need this information. It's the 49ers' offense [and they were] probably not drafting a quarterback. But it came full circle."

Now Lock must continue to process his playbook and transfer the play call from the headset to the huddle — and then to the play itself.

As he works toward proficiency, he said he'll evaluate his progress on a daily basis.

"I'm going to take it day by day for right now," Lock said. "Obviously, trying to better myself, but at the same time when the vets get here, getting to know them and getting to talk to them. Just [trying] to be the best teammate that I can. I'm probably going to take it day by day and evaluate myself every day. [I will] figure out what I need to do better and keep a book running of the things I thought I did well that day and try to take it to the next day with things I need to fix."

In the meantime, Lock will continue to enjoy days like Friday. As he explained after his first practice with his new team, there's hardly a better feeling.
