What happened: PFF released defensive grades for first-round rookies through the preseason, with Arvell Reese leading the group at 88.2. Akheem Mesidor followed at 81.6, Malachi Lawrence graded at 74.8, and Keldric Faulk rounded out the four at 73.2.

Why it matters: Reese's grade tracks with his early camp workload, where he's already logged punt-coverage snaps as the lone first-round defender tracked on special teams. Mesidor, who won two camp reps against Alt, sits close behind at 81.6, while Faulk grades lowest of the four as he continues adding reps at three-technique for Tennessee.

What to watch: Grades will continue shifting as each rookie logs more preseason defensive snaps.
