Ravens coach John Harbaugh has had to talk about the team's injury problems a lot this week, probably more than he'd like to. But he's been around long enough to know one thing in re the injuries -- other teams won't feel sorry.

"Yeah, we've always said that," Harbaugh said in a press conference earlier this week. "You can complain all you want but nobody cares. Nobody is going to feel sorry for you."

The Houston Texans are not going to take it easy on the Ravens Sunday because they're missing two key players on defense. Why? Well, that's not life in the NFL.

Houston has its own goals to chase and problems to solve. The Texans were embarrassed on national TV last weekend. Green Bay made them look bad. They're going to want to look good this week.

The Ravens? Well, the question now is who's going to come through for them. That's what Harbaugh talked about after saying he knew no one's going to cut them a break.

"It’s an opportunity," he said. "You know the old saying: ‘When one door closes, another door opens,’ right? We’ve all heard that since we were kids, and that’s true. There are going to be opportunities for guys to [step up]."

Harbaugh said Ray Lewis would challenge players by saying "what's your legacy?" Players can determine that by coming through at times when their team needs them or at the right times.

Right now, the Ravens simply need people to step up because of all their injuries. Their schedule won't get any easier, and the opponents won't be any nicer.

"[They have a chance] to determine their destiny a little bit, and it’s going to be fun to see which guys step up," Harbaugh said. "We’ve got some guys who we are excited to see step up.”
