As a second-round pick in the 2019 NFL Draft, Marquise Blair figured to have a major role in the Seattle Seahawks secondary. Through a combination of an unfortunate knee injury and the depth ahead of him, that has yet to materialize.
In his rookie season, Blair essentially only saw extended playing time on defense due to injury. Through six games he only played 12 defensive snaps. Blair replaced Bradley McDougald and started against the Baltimore Ravens, then he subbed in for Quandre Diggs (after Tedric Thompson went to IR) for two more starts as Diggs nursed a hamstring issue he had while with the Detroit Lions.
