The extent of Dart’s knee injury was not initially understood, but further testing showed a serious injury to his MCL and PCL. He’ll be sidelined for the rest of the season, effectively ending the Giants’ season. Jameis Winston will likely take over as the team’s starter. It’s a letdown for Dart, who started the year hot against the Cowboys. In relief of Dart in Week 2, Winston was 25 percent below his expected completion rate, the worst mark in the league. Look for the Giants to be a run-heavy, hyper-conservative offense going forward with targets concentrated between Isaiah Likely and Malik Nabers. Winston might be usable in superflex formats for now.
