What happened: PFF placed Khalil Mack’s Chicago Bears opener among its 10 highest-graded NFL team debuts. A Jacksonville Jaguars debut from 2011 also made the list.
Why it matters: Chicago finished 12-4 and won the NFC North that season. Mack’s immediate impact validated a major late-offseason acquisition.
By the numbers: Mack’s 93.4 grade topped Jacksonville’s 2011 mark by 0.4 points. His opener included a sack, forced fumble, fumble recovery and interception-return touchdown.
What to watch: Future team-debut grades will determine how long the two marks remain in PFF’s top 10.
