I know I read he was one of the finalists, so I guess after not getting it he moved on to find a possible head coaching job somewhere else.
Yes we need some big improvements in the secondary, Oline some but not nearly as much as the secondary. Hopefully we can pick up a few players to fill some voids in there. I'm glad they chose a guy with good defensive roots to be the new head coach, and a guy who understands the importance of the ground game in Pittsburgh. I think Tomlin + LeBeau = watch out AFC offenses. Hopefully he has some scouting skills, but since he did coach DBs at Tampa Bay during the Super Bowl year things look good on the improvement of that secondary.
