49ers' QB change does not appear temporary

Posted by ESPN.com's Mike Sando

HOUSTON -- Alex Smith's second touchdown pass to Vernon Davis in three drives as the 49ers' new starter cements his status as the top quarterback beyond this game, I would think. Smith

Smith appears poised and under control. He appears decisive. The pressure is off and he is responding.

The offense has responded well to Smith. Josh Morgan and Michael Crabtree are making plays on third down. Davis is working the middle of the field.

The outlook is suddenly much brighter for the 49ers, even as Andre Johnson is getting open deep for the Texans as I type this.

Smith has shown good instincts in this game, sensing the rush and knowing when to scramble. He looks good so far.

By the way, the Texans' Johnson is down with an injury right now. Not sure the severity.
