The biggest example of that came when Justin Fields made his NFL debut against the Cleveland Browns.
Fields faced the Browns, who had Myles Garrett and Jadeveon Clowney on the defensive line. Let,s just say experienced some welcome-to-the-NFL moments in his starting debut. The rookie was slow in reacting to situations, leading him to either release the ball late or take the sack.
The play-action and run-pass option schemes they were running were head-scratching because the Browns already knew what would happen. In the end, the Bears lost that Week 3 game, 26-6. It was not pretty and I put almost all of the blame on matt Nagy.
Fields finished 6-of-20 passing (30%) for 68 yards without a touchdown or an interception. His rating was 41.2. Meanwhile, the Bears' poor play-calling led to nine Browns sacks, 4.5 of which were from Garrett.
