Jerry Angelo and Lovie Smith have been criticized during their tenure with the Bears for failing to acquire and develop talent, but their depth has improved in 2010. ''You've got to have depth,'' Brian Urlacher said. ''You're going to have guys go down during the season. It's nice to have guys step in and do a good job for us. Tim did a good job last week, made a couple nice hits out there, some good tackles. He missed a couple, but we all missed a couple last week. That's going to happen in the NFL. But it's nice to see guys step in.'' ''It says we have good depth,'' Smith said. ''Each year, of course, you're tying to get that best group together. But some years, it just doesn't work that way. ''During the course of a year, injuries come up, all different type of things come up, that will make you go to the next guy in line. Players realize that, too, especially some of the guys who have been around here for a while. We keep telling them, 'If you deserve to play, eventually something will happen where you get an opportunity to do that.' We've talked about the depth an awful lot. Now, we're getting a chance to really, not just talk about it, but see that depth come up.''
