One of the criticisms of Cutler during this time was that he made poor decisions on the field and tended to force throws into tight coverage, resulting in interceptions. Additionally, there were concerns about his mechanics, specifically his footwork and accuracy. Some analysts suggested that Cutler's lack of mobility and tendency to rely on his arm strength rather than proper technique contributed to these issues.
Another factor that may have contributed to Cutler's decline was the constant changes in the coaching staff and offensive scheme during his tenure with the Bears. He played for multiple head coaches and offensive coordinators, making it difficult for a quarterback to establish continuity and consistency.
Injuries also played a role; Cutler suffered injuries that made him miss games and impacted his performance.
Finally, the lack of talent around him on his teams, particularly on the offensive line and at wide receiver, could have also hindered Cutler's performance. Without a strong supporting cast, it can be difficult for any quarterback to succeed, even a talented one like Cutler.
Overall, multiple factors likely contributed to Jay Cutler's perceived decline as a quarterback in the NFL.
