Urlacher/Briggs/Tillman/the Browns, then drafting Tommie Harris and trading for Ogunleye before Smith even coached a game? He came into a lot of budding stars on that defense.
Sure, but there's also some chicken or egg. Did those players have that kind of success entirely on their own or was the system a part of it?
Urlacher - Former safety, so the cover 2 was so good for him.
Briggs - He only had one year before Lovie and all of his real success happened with him. Briggs was great, but some of his success had to be the coaching he received and the positions he was put in.
Tillman - Same story as Briggs. Rookie year with one coach then his career took off in the Lovie cover-2.
Mike Brown - Missed a lot of time. Played 6 games in their 13-3 Superbowl loss season. Still a great player, but was battling his calf injuries at that time.
Harris - Could be injuries, but he really had no success outside of Chicago, which let him be a hunting 3 technique.
Ogun - Good player. Not great, but good.
A. Brown - It was like having a home grown Ogun. Nice player, but let's remember he never had more than 7 sacks in a season.
Anyway, there were absolutely some players there, but that's the way with all new coaches. Their job is to get the most out of them and I'd say for the guys you mentioned he did a good job at that. Offensively it's a different story...
