The Texans were linked Daboll and Eberflus last year and they know McDaniels, so one or the other didn't want any part of the Texans process again. Leftwich, Bowles, Mayo, Ryans of course I don't have a real clue as to why they didn't interview, but it is interesting they are all minority candidates and the Texan were bleeping around with Hines Ward to satisfy the Rooney rule.
More broadly we know almost nothing about any of these dudes as candidates for head coaching outside of :
1) Their side of the ball performed well.
2) We are told by some source about their leadership, communication, etc,
Speaking of names what has happened to Eric Bieniemy?
