Alex Smith's QBR in 2018 was 46.9. Case Keenum's QBR in 2019 was 45.6. Haskins's QBR in 2020 was 24.8, and Smith's that year was 28.2. Heinicke in 2021 was 45.8. Wince in 2022 was 34.4 and Heinicke was 46.5. Howell is currently 20th in the league this year at 46.8. IMO, very impressive considering he's only started 7 games. It does appear that he is on track to be the best QB this team has had since Kirk (for reference, Cousins had the following QBR in 2015: 67.8, 2016: 66.5, 2017: 56.2).
