Very disappointing hire. I was really looking forward to having some new blood in the organization who wouldn't be happy as a pig in chit with 9 wins per season and a first-round shellacking on the way to making tee times for the off season. You know...some hope for a change? Nah! Lazy hire by Rooney and an ownership group that is perfectly fine with the worst facilities in the NFL, nine wins on average, and early exits from the rare post season.
It is also possible that nobody else really wanted this job. Face it, the Steelers team is a mess and a half. No matter who they call the HC he's going to have a rough start here for a couple of seasons with no QB, poorly performing OL, aging (or aged) defense, etc. The HC might feel like a fall guy, so while other opportunities abound why walk into that mess?
