SAN FRANCISCO (AP) As Alex Smith stood on the sideline with a concussion, San Francisco's potential quarterback of the future went to work - and fast.
The concussion suffered by Jay Cutler overshadowed some elements of the game played by the offense.
But not all.
A significant key to Sundays Bears-Houston Texans game: length of field. If it is the same for both teams, the situation tilts in favor of the Houston Texans. And the Bears offense knows it.
The Bears prime directive each game is rendering a team one-dimensional. That will be difficult to accomplish in the case of the Houston Texans. Very, very difficult.
Its the famous old saying: You can take the boy out of the tight end but you cant take the tight end out of the boy.
