The Chicago Bears offense combined to run for 158 yards last week in Denver.

Marion Barber had 108 yards, while backup Kahlil Bell had 40 yards and quarterback Caleb Hanie had 11 yards.

Barber and Bell had success on the ground, but mistakes in key parts of the games led to the Bears loss.

Barber was pushed out of bounds with under two minutes giving the Broncos another chance.

In overtime, Barber had a huge opening and tried to push through it, but failed to cover up the ball and lost the ball and ultimately the game for the Bears.

Luckily the Bears team was supportive of Barber.

Barber knows he needs to get better.

With one-year left on his contract, the Bears want Barber to succeed, but wouldn’t be afraid to cut ties with him if he falters more down the stretch.

Barber has 389 yards rushing and six touchdowns on the season, while Kahlil Bell has 97 yards rushing on the season.

The Bears run offense is averaging 122.5 ypg, which ranks 9th in the NFL. They average just about 27 carries per game and 4.4 ypc.

Unfortunately the surging Seahawks are coming to town.

Winners of two straight, Seattle has the 11th ranked run defense in the NFL.

They allow an average of 104.3 ypg on the ground and an average of 3.7 ypc.

The longest play allowed on the ground on the season by Seattle is 32 yards.

The Bears are going to have to run well to have a chance to win.

With a shaky passing game led by Caleb Hanie, the Bears offensive success starts on the ground.

Running early and often on the Seahawks is going to be key tomorrow.

Barber and Bell have shown they can run the ball successfully with Forte on the sideline healing up.

Barber needs to fix some of the mistakes he’s made the past couple of weeks.

The seven-year veteran knows better than to run out of bounds in a key situation against Denver or line up improperly like he did against Kansas City.

Tomorrow at Soldier Field, the Bears know its a must-win scenario.

Expect to see two running backs pumped up and ready to go.

Barber and Bell want to show what they have especially against an above average run defense in Seattle.
