The poster child for young quarterbacks getting ruined by being sacked too often early in their career is David Carr from the Houston Texans. During his first two years with the expansion Texans (2002-2003), he was sacked 11% of the time while appearing in 28 games. So far, in 18 career games, Chicago Bears' second-year quarterback Justin Fields has been sacked 13.3% of the time.
Carr's sack percentage improved from 14.6% to 4.8% from his rookie to sophomore season, while Fields' is at 16.7% in 2022 after being 11.8% as a rookie.
Houston's pass protection went back to being horrific in 04 and 05, making it difficult for Carr to develop properly, which is the same fear many Bears' fans have about the trends we're seeing in Chicago.
