Highest defensive grade this preseason among rookies (min 20 snaps) Kamari Ramsey 94.8 Jacob Thomas Via @PFF on X

What happened: PFF applied a minimum threshold of 20 defensive snaps. Jaishawn Barham earned a 90.2 grade, while Arvell Reese posted an 88.2 and Mory Bamba an 86.0.

Why it matters: The grades offer an early measure of which rookies could earn larger roles when the regular season begins. Preseason evaluations remain limited samples as teams settle their opening rosters.

By the numbers: Ramsey leads Thomas by 2.1 points and Barham by 4.6. The gap from Ramsey to Bamba is 8.8 points.

What to watch: Final roster decisions and early regular-season usage will show whether the preseason grades translate into meaningful roles.
