Two undrafted rookies headline a day of roster-theater for Detroit, as Day 16 of training camp resembled a scrimmage with implications for the 53-man cut. Kennelly flashed with first-team reps, delivering run stops and a blitz breakup that caught eyes in a crowded depth chart. Cooper answered with robust run stops and a later tackle-for-loss, hinting at versatility along the front. The Lions scrimmage-like drives exposed improved competition across offense and defense, with Gibbs and Montgomery splitting touches and St. Brown and Jameson Williams making timely plays in the red zone. Hutchinson leaned into pressure, while Robertson and Ya-Sin varied their coverage clips. Branch and Joseph showed aggressive instincts that could push youngsters for snaps behind them. The tempo with Hooker and Goff orchestrating drives from the goal line outward produced several scoring moments, including a St. Brown TD and a few red-zone successes. With Mekhi Wingo’s return looming over roster math, Detroit’s defensive line depth could tilt in subtle but meaningful ways as joint practice with Houston looms.
