The Facts: O'Sullivan made such a strong impression during the team's just-concluded mini-camp that HC Mike Nolan said he would get the former UC-Davis standout some action with the first-team offense when practice resumes next month. "It's a three-man race, not just two," Nolan said.

Diehards Line:O'Sullivan had a head start over Alex Smith and Shaun Hill during these five practices because he was the only QB with experience in OC Mike Martz's complex system. O'Sullivan's experience with Martz is part of the reason the 49ers signed him in the first place. ... Still, Smith remains the early favorite to nail the job down.
