There are many reasons why the Broncos blew an 18-point lead to the Washington Commanders on Sunday. Their inability to stop Commanders quarterback Sam Howell’s screen passes was one of them. Denver was clinging to a 24-21 lead at the start of the fourth quarter when Howell threw a short pass to his left to running back Antonio Gibson, who had plenty of green grass in front of him as he sped down the field for 36 yards.
