Barber's first miscue came with the Bears leading 10-7 with about two minutes to go and the Broncos out of timeouts. Barber, who ran hard all day and gained 108 yards on 27 carries, inexplicably went out of bounds, stopping the clock. It eventually gave the Broncos extra time, and they moved in for a game-tying field goal, a 59-yarder by Matt Prater that forced overtime.
"Definitely one of the toughest ones I've had to deal with, we've had to deal with," Bears coach Lovie Smith said Monday. "We normally celebrate when we have a game in control like that late in the game. We haven't been in this position very often, if at all. We don't like it, but it's how we respond, and we will respond."
Barber drew the ire of fans and commentators for the two plays, but his teammates didn't hold the mistakes against him.
Smith said blaming only Barber for the clock blunder, let alone the outcome of the game, was unfair.
"It's on all of us," Smith said. "Yes, it's a coaching thing. But it's on our team, on Marion, on us, on all of us. It's a situation that shouldn't happen, but it did, and we're all suffering the consequences for it."
