Whisenhunt wary of Gore

Coach Ken Whisenhunt admitted Wednesday that he didn't know much about 49ers running back Frank Gore before the Cardinals played the 49ers last year.

Whisenhunt was in his first season with the Cardinals, and Gore didn't play much last preseason because of a broken hand.

Gore didn't do a lot in the teams' first meeting, which came in the season opener, but he exploded for 116 yards rushing and 98 yards receiving in the second game. He also scored two touchdowns.

"He kind of ripped us up pretty good," Whisenhunt said, "so I said, 'Wow this is why they talk about him the way they do.'

"He's an outstanding football player. The more I see him, the more I understand what a dynamic player he is. He is really somebody you'd better account for, or he's going to really hurt you, whether it's catching the ball out of the backfield or even on the run game."
