Bart Starr Hoping To Attend Week 2 Game vs Vikings
So you don't have to read the entire report:
"Bart Starr is not only a Green Bay Packers legend, but he's also one of the legendary figures of today's NFL as was the first Super Bowl MVP. And it's very possible Packers fans will get to see Starr again when the Packers hit the field this fall.
Starr's son, Bart Starr Jr., attended the Packers Hall and Fame banquet and he announced that his dad and mom are hoping to attend the Packers Week Two matchup against the Minnesota Vikings (via Rob Demovsky of ESPN). Bart Starr Sr. has had his share of health concerns over the years but during the Hall of Fame banquet, a video was shown of Starr throwing a football.
The last time the Pro Football Hall of Fame quarterback was in Green Bay was back in October 2017 when the Packers took on the New Orleans Saints. Starr's wife, Cherry then announced that it would be the last time the two would travel to Green Bay due to health concerns. The couple currently resides in Alabama, a place where Bart Starr was born and raised."
