The San Francisco 49ers were their own worst enemy in a 19-10 loss to the Chicago Bears on Sunday.
Sunday’s loss dropped the 49ers to 2-4 in season openers under Kyle Shanahan. The two seasons they won on opening weekend culminated in a trip to the Super Bowl and NFC Championship Game. The four seasons they lost ended in losing records.
On Sunday, the 49ers defense played lights out during the first half, holding Chicago scoreless while giving the offense the ball with terrific field position.
The deepest San Francisco’s offense started the first four possessions was their own 36.
