SUMMARY: LB Keith Bulluck is a believer that you need to work out mistake during the week at practice to eliminate them on gameday. "Practice is to make mistakes. You’re gonna make mistakes in practice, but sometimes, after those mistakes, if you make them in practice, when you go to the game, you shouldn’t make them," Bulluck said. "We keep making the same mistakes." Bulluck says he's frustrated that some players are not putting in the extra work to improve a defense which has struggled so far this season. "When duty calls, you’ve got to be able to go out and perform," Bulluck said. "That’s why a lot of this stuff is frustrating, because we’re all out there practicing and working and maybe people aren’t putting in the extra time at their jobs. Maybe they’re not doing the extra things like watching film and studying their opponent harder. These are things that I do that I’ve always done. I don’t know. You’ve got to do the extra things that are going to separate you from the rest of the pack." What do you think about this article? Post your comments below.
