On Thursday, the Houston Astros announced some changes to their leadership structure and front office. Normally, these go unnoted unless they involve a change at general manager. Yet in this particular instance, those involved have some familiar, noteworthy names. 

To begin with, Hall of Fame pitcher Nolan Ryan let various media personnel know that he will not be returning to the Astros as an executive adviser to owner Jim Crane. "I will not be back with the club and will leave it at that," Ryan texted to Mark Berman of Fox 26, among others. 

That within itself doesn't seem too important, except Nolan's proclamation comes on the same day that his son, Reid Ryan, was demoted from being the team president to being the executive adviser of business relations.
