I thought the lessons learned from the Chip Kelly and Eagles experiment was enough to convince NFL owners that unless your HC is Bill Belichick, it's a bad idea to have your HC as GM or with so much control over personnel. Obviously, the Texans heard "Bill" and didn't listen to the warning.Interesting analysis but in my own humble opinion I think some day in business schools throughout the country they will be studying
the Bill O'Brien story in Houston as a classic example of the Peter Principal.
O'Brien has been a reasonably capable HC in the NFL here in Houston but when promoted to GM the wheels came off with some of his decisions as it's hard to argue the Texans roster became stronger and not weaker since his promotion.
And to make his new position even more challenging O'Brien was to also continue as HC after becoming GM.
