No matter who they hire as HC, there will be some degree of discontent on this board, expressing a dysfunction within the organization. And of course there will still be those who believe the McNairs can, or will, never will be good owners and only want a change in ownership. And of course there are the NC haters.
You are well aware of the underlying improvements made within the Texans organization, having pointed these out in the past. And I haven't seen any expression of discontent with the quality of HC candidates on the Texans list. It's a solid list.
But even you express in your comment, if they don't hire a coach you favor, this will be a sign of disfunction within the Texans. The perception of disfunction will likely always be here, although winning may subdue it momentarily.
