Struggling Carolina quarterback Bryce Young slumped his shoulders after overthrowing open receiver Jonathan Mingo for what could have been a 45-yard touchdown just before halftime Sunday. It was one of many squandered opportunities in an ugly 28-6 loss to the Saints, who played poorly enough to draw boos from the home crowd several times. After completing fewer than half of his passes for the first time last week at Tampa Bay, Young barely completed a third of his attempts against New Orleans, finishing 13 of 36 for 137 yards as the Panthers dropped their sixth in a row.
