He had helped his team to a 24-27 victory in their season opener against the Chicago Bears, recording 143 passing yards and three touchdowns. However, he could not improve on this performance on Sunday night.Against the Falcons, J.J. McCarthy completed just 11 of 21 for 158 yards and no touchdowns. He also threw two interceptions that led to the Vikings suffering a humiliating 6-22 loss at home.During his rookie debut last season, McCarthy missed out on the entire season due to an injury. Sam Darnold took over as the QB1 and led the Vikings to a 14-3 record and a spot in the playoffs. Unfortunately, they lost to the Rams in the Wild Card round.
