Alex Smith admitted he was “disgusted” with himself after reading his quote about Michael Crabtree in the news last week. Smith was asked why Crabtree was not attending the team’s workout sessions and Smith said, “Good question. Honestly, I don’t know.”

It read like a kiss off and Smith immediately called Crabtree to apologize. On Monday, Crabtree seemed to return the favor, saying he was not sure who the 49ers quarterback was going to be. Smith had an answer for that too, saying Crabtree doesn’t necessarily read about the team and that he probably missed Jim Harbaugh’s rather adamant stance that if he was a betting man, he would wager that Smith would beat out rookie Colin Kaepernick for the starting job.

But where does that put veteran backup David Carr, the only quarterback on the roster signed (although it would be a huge upset after putting in this much effort, if Smith didn’t sign). Carr has been told he will be allowed to compete for the starting job.

“They (49ers coaches) told me they are going to roll the balls out there and the best player is going to play,” Carr said. “I like that situation.”

Smith and Carr seemed to split the snaps during Thursday’s final day of minicamp, the only practice the media was allowed to watch. And while Smith is organizing the offense and has received power point presentations of plays from the team during his April 29 meeting with coaches (the one day the lockout ended), Carr has actually worked in offensive coordinator Greg Roman’s system for two years (2004-5) in Houston when Roman was the quarterbacks coach and Carr was the starter.

Carr described the Roman-Jim Harbaugh system as a blended offense between West Coast and other concepts, but the language is distinctly West Coast. “That’s the easy part,” Carr said of re-learning Roman’s nomenclature. “The hard part is getting these guys lined up.”

Carr was basically assured he’d compete for a job last year after then general manager Scot McCloughan signed Carr and traded Shaun Hill. But it became clear that then coach Mike Singletary was not a Carr supporter and the former Fresno State standout never got a chance.

“Last year, it was a little bit different,” Carr said diplomatically.

Carr described Roman as super smart and passionate. “He’s a grinder … He takes it very seriously. He not only cares about you as a player but he cares about you as a person.”

NOTES: Former San Jose State wide receiver Kevin Jurovich looked excellent in Thursday’s practice. Jurovich was instrumental in finding a practice home for his 49ers teammates at the school. … When asked who stood out during the four days of minicamp Smith said the veteran receivers which includes Jurovich, Josh Morgan, Kyle Williams, Crabtree and even the injured Dominique Zeigler. … Williams left Thursday’s practice early with a leg pull but he said it was not serious. … Smith thought about asking Steve Young or Jerry Rice to view practice and teach some West Coast principles, but he said the offense has evolved quite a bit since their day and Smith has yet to reach that level of detail. … Smith said he taught more of a volume of plays and concepts than a standard 49ers minicamp. … Smith encouraged Crabtree to sit out the rest of minicamp after a pair of cleats he was wearing Monday caused football soreness. Smith said the last thing he wanted to do was get someone hurt. … The defense, led by defensive end Justin Smith, ran sprints up a small hill just behind the stands for over 40 minutes. … I asked tight end Delanie Walker to clarify his remarks Tuesday when he said he would be working out in the slot more. Walker said he will remain as a tight end but will probably motion to the slot often, which is something he did quite a bit on Thursday. … Barring the end of the lockout, Smith would like to put on another minicamp at the end of June.
