Lovie Smith got hired because by all appearances the Texans fired Culley unfairly to bring in McCown, who I don't believe has coached in any capacity, as their HC. Flores' lawsuit came out and the clownshow leadership over there actually had a cogent thought and said "I don't think we can pull off this obviously nonsensical move this year without becoming the poster team for hiring discrimination" so they pivoted and acted like Lovie had been their double secret probation candidate all along.
