Regressed: Too many fumbles
While Darnold threw fewer interceptions, he fumbled the ball more than twice as often as he did in 2018. He fumbled 11 times in 2019, and fortunately only lost the ball three times. That’s discouraging for a young quarterback known to use his legs a lot.
Darnold was always known as turnover-prone in college, and he fell back into his bad habits in 2019 on the fumbling front. He needs to learn how to hold onto the ball if he wants his offense to stay on the field.
