Current/Former HC Options for Texans if Lovie gets the Boot

My thoughts/preferences on our coaching options if we decide to part ways with Lovle. All the names on this list would be a significant improvement from what we have today. All three of these names have prior head coaching experience,

• Mike McDaniel. He could be fired by the Dolphins. I don't think you can blame him for the team's franchise QB being unable to stay healthy for a year. I think he would be a great coach as we rebuild the team, and would be great to work with Mills or whatever QB we draft. He would be a significant improvement on offense.
• Jim Harbaugh. He took the 49ers to three NFC championship games and a Super Bowl with average QB play. He'd be a significant improvement.
• Sean Payton. Let him pick his staff and pick his QB to coach up.
