Three first-half questions on Cards-49ers

SAN FRANCISCO -- Have the 49ers scored enough points, 10, off all these Cardinals turnovers? A 10-point deficit is nothing for Arizona if the Cardinals protect the ball.

What was referee Jerome Boger thinking when he determined Larry Fitzgerald did not catch that pass near the 49ers' goal line? Sure looked like a 45-yard reception or a 46-yard touchdown, although I could not see every aspect of the play. It's nice when referees explain things. Boger is having a rough night so far.

Have the 49ers discovered how to work Frank Gore into their new-look offense? It's looking that way. Gore has run effective from base personnel. The 49ers have gone away from their base personnel in recent weeks. It's back with in a big way so far in this game.
