Alex Smith is an expert. So says Jim Harbaugh, and he's the one who truly matters on this topic.
Harbaugh figures it typically takes a quarterback two full seasons in a new offense to become a so-called expert.
In the case of Smith, however, he's already right there if you ask the 49ers coach.
Smith got a chuckle out of hearing that the reigning NFL Coach of the Year was dishing out such high praise after practice Thursday, and he hardly believes he has mastered Harbaugh's unique version of the West Coast offense.
While Harbaugh says his starters might play more in the team's second preseason game Saturday at Houston, he has already seen plenty from Smith on the field to be confident as his second training camp winds down.
