I think his statements and logic are obvious. Like Pat Summit used to say, focus on what you can control. HT is not something JH controls. Make him feel welcome, show him how he might fit in to the new team, then if he isn't interested, go play football. Coach's approach is pretty healthy and is what successful people do. Fans, for some reason, seem to want to see more lamentations and gnashing of teeth from coaches. I remember that ridiculous time when the Knoxville media wanted Butch to say, "The team failed." Butch, to his credit didn't bite and posters on this site were among those piling on, trying to get him to tell players they had failed when there was no benefit in doing so.
Heupel is telling the team that they don't need Henry to be successful. I don't understand why any fan would think that was a bad thing.
