Las Vegas trimmed its safety depth after releasing Thomas Harper from the initial 53-man roster, then brought in Tristin McCollum. Harper was claimed by Detroit, giving the Lions a flexible defender with late-2024 momentum. Vegas hinges on Jeremy Chinn and Isaiah Polo-Mao to anchor the back end, a unit facing depth issues as Week 1 looms. This reshuffle signals ongoing defensive tinkering in the Raiders' secondary and potential snap changes for early-season games.
