The long-standing friendship between Texans coach Bill O'Brien and Doug Marrone dates back to their days on the Georgia Tech campus.
Both were assistant coaches under George O'Leary and carpooled to work together.
Marrone and his wife, Helen, introduced O'Brien to his future wife, Colleen, who was roommates with Helen Marrone at Boston College following a Georgia Tech overtime win over North Carolina.
With the firing of Jacksonville Jaguars coach Gus Bradley following a 21-20 loss to the Texans at NRG Stadium, Marrone has been installed as the interim coach. He'll also be a candidate for the full-time position.
