John and Kathy Osweiler had last Sunday circled on their calendar for nearly seven months.
As residents of Phoenix, they can't get to all of their son Brock's games. But during the 25-year-old quarterback's four-season career, they tried to make it as often as possible -- both in the preseason, when he played regular snaps, and at times in the regular season.
When the 2015 schedule was released in April, the Week 11 game in Chicago presented the perfect opportunity for a family reunion on the road.
"Being the fact that Chicago is the place where Brock played his first preseason game [in 2012], and that it was his birthday, we went ahead and booked the trip," John Osweiler said.
