Part of the problem may be self-inflicted. Next Gen Stats show Wilson and Fields in particular hold the ball too long according to NFL Media's Daniel Jeremiah.
The reason for this could be due to personnel issues and scheme issues as well. For the Bears, Matt Nagy rolled out Fields as a starting quarterback and basically asked him to be "Dude who backs up Andy Dalton" instead of "Insanely Athletic First-Round Selection Playing Behind Bad Offensive Line." The decision to use Fields was to make life easier for Fields. Take the pocket and move it. Take him away from the edge. Cut the field in half. To make the odds work in your favor, run several RPO's while playing an offensive team that's not so great.
Although the Browns are a solid defense, the offensive coach let a young quarterback to score 6-for-20, generating 47 net yards over 42 plays (1.1 per player). One net passing yard. That is not a typo: the Bears had just one passing yard. In 2021. A full football match. There were 11 players on the field. Fields was kicked nine times. Did you notice? Nine times. Wake up and take a whiff of the coffee, Mr. Nagy.
