Green Bay Packers quarterback Aaron Rodgers said Sunday night’s mass shooting in Las Vegas was “very scary” to wake up to Monday. Rodgers said he saw the news on social media shortly after awakening at 6 a.m. Monday. His initial reaction, Rodgers said, was being “heartbroken” for the victims and families. For Rodgers, the event became more personal than he could have expected. “I have some ties and connections to Vegas,” he said, “and I had some friends who were at the venue. It’s unthinkable that this would continue to happen in our country. You obviously send your prayers and thoughts to the people who are affected. “A friend of mine lost their best friend of 20 years.” Rodgers did not specify which friend he was referencing, or the victim. The Packers quarterback called for safeguards to make mass shootings less frequent. “We’re going to have to make some changes in society,” Rodgers said, “hopefully quickly because there’s too many situations like this where we send our thoughts and prayers to these victims, and unfortunately it keeps happening.” Quarter masters: The Packers put themselves in position to contend for a solid playoff seed in January, but coach Mike McCarthy knows the next four games are important if his team is to benefit from its solid start.
