Good for Flores. I thought his lawsuit would certainly spell the end of his career in the NFL, and it's appropriate that it's Art Rooney's team who hires him.
I don't bear any ill will towards Flores. I believe he's a dick because he was taught by a dick that being a dick is the path to winning. Maybe he can learn and grow under Tomlin.
If NFL teams were compared to corporations, then the Steelers are like Disney. Fan friendly and the players and coaches are expected to conduct themselves on and off the field in a proper manner. Cutting up will not be tolerated. I'm sure Steelers ownership clearly explained that to Flores before they hired him and Flores agreed to those terms. He's a position coach now so he doesn't have final authority. Whether or not he can work his way back up to a head coaching job remains to be seen.
