McNeill might have been one of the most improved players of the 2023 season. The former third-round pick went from earning a 69.8 PFF overall grade in his second season to an 86.9 mark in 2023, which ranked seventh among interior defenders. He was one of just six players at the position to earn 75.0-plus run-defense and pass-rush grades last season.
I assume this is just based off of last year. Bc Adebo was lights out last year but I think he was the worst, or at least one of the worst, graded CBs in 2022.
