Alex Smith was asked Monday what percentage of Mike Martz's offense has already been installed.

"I'd like to say a lot," Smith said.

Smith is the wrong person to ask, but he knows this is the most he has been asked to learn at this stage in the offseason.

Smith took the reps with the No. 1 offense on Monday, the first day of the club's organized team activities. Smith is competing for the starting job at quarterback against Shaun Hill and J.T. O'Sullivan.

Smith, the No. 1 overall pick in the 2005 draft, is the prohibitive favorite to win the job. On the practice field, he clearly stands out as the most talented player. He continues to round into shape after surgery in December. Though he is not quite 100 percent, Smith is making steady progress and says he can make all the throws required of him.

Now, Martz has to find a way to get more production from Smith during the games.

Martz is Smith's fourth offensive coordinator in four NFL seasons, and Martz is different unique in his approach. This is the most work the 49ers' offensive players have been assigned for an offseason. Smith said playing football will require hours and hours of study at home.

As far as learning the playbook . . . well, that might never happen. It's a never-ending process - a book that never ends, one reporter suggested. Martz is always adding plays and making adjustments.

"He demands a lot and expects a lot," Smith said.

Here are some of the questions-and-answers from Smith's meeting with the media after the first day of the 49ers' organized team activities:

QUESTION: How have you tried to learn this new system?

SMITH: Anyway you can. Obviously, you go over it. You're obviously listening to the coaching. Coach Martz is there with everyone, going over it. Then, obviously, (we) look at quite a bit of film - a lot of cutups. And then coming out here and practicing it. Coming out with receivers and throwing routes. So when we come out and do some team reps, we can execute it.

QUESTION: When you watch film are you watching Warner, Bulger, Kitna?

SMITH: Yeah, everybody - a lot of different quarterbacks. There's a lot of Rams footage out there, a lot of Lions as well. It's a mixture of all of it.

QUESTION: Are you at the point when you see a play on film, you know exactly what it is?

SMITH: The stuff we've done. Right now, there are a lot of cutups. With as much as we've put in, yeah, you can definitely recognize it and recognize a lot of what we've put in.

QUESTION: It looks like you're rolling out and moving more than those other quarterbacks with the Rams and Lions. Is that the case?

SMITH: Maybe. It's just something where you're trying to play to different strengths, maybe. It's something we've done here in the past. We have rolled out a lot and done a lot of movement. I think (Martz is) maybe incorporating that and watching some of the stuff we've done and been successful with. It adds another dimension. He doesn't want to be cookie-cutter. He's trying to mold it to the strengths here.

QUESTION: What are the things you emphasize in your mind that you have to do well in this offense?

SMITH: Executing is No. 1. For the quarterback, it's the clarity - understanding and being comfortable with it. So when we come out here and take these reps, you're really letting go and cutting loose and playing fast. You don't want to be out here thinking. I'm battling that right now. (I) try to be prepared to come out here and play fast.

QUESTION: Are you at the point where you can cut loose?

SMITH: With some stuff. Some of the stuff that's been in since the jump, I feel more comfortable with, for sure. Some of the stuff that was new today, that'll come with time.

QUESTION: Technique-wise, how much has Mike worked with you and does the stuff he's thrown at you still feel foreign?

SMITH: Yeah, we've all worked hard on the fundamentals and worked hard on the things he's emphasizing at the quarterback position - things he wants to see out here. Some are more comfortable than others and some are more foreign than others. That's the stuff you try to come out here and work on your own on our stuff, so when you're doing team reps, you're just playing. You don't want to be out there thinking about fundamentals. You want to be thinking about offense and defense.

QUESTION: How is the new offense different than the old one?

SMITH: It's hard to say. I think we do a lot. We do everything. Every style of offense you can imagine, we have a piece of that in there, it seems like. We're trying to incorporate as many different things as possible and give defenses as many different looks as possible. We're pushing that envelop.

QUESTION: There was an article about Tom Brady and Tom Martinez, his personal QB coach, around Super Bowl time that noted the lack of fundamentals you'd been taught at the NFL level. Do you expect that to change with Mike Martz here?

SMITH: All coaches coach fundamentals, and obviously each coach is different. Yeah, (I'm being taught) quarterback fundamentals, especially things that coach Martz wants to see that will help us be successful in this system. Coach Martz has spent a lot of time analyzing what it takes to play well in this and what you need to do and stressing those fundamentals -- what your feet need to look like, body posture, different things like that. You're constantly getting coached out here in all that stuff.

QUESTION: Is there a need now to seek outside coaching on your fundamentals?

SMITH: No. Obviously, I have enough coaching as I can handle out here. This is what I need to be focusing on. I don't need to be working on any fundamentals outside of this. This is where I need to be focusing my attention.
