Netting will keep out hawks but not raccoons and other predators with sharp teeth. They'll chew right through netting. However, most predators of that nature tend to be nocturnal, so some people roof their runs with netting to keep out hawks and lock their chickens inside a secure coop at night.
Rather than burying wire, you could make a wire apron attached to the base of the run extending two feet outwards. Stake down the apron with landscaping staples or anchor it with stones, etc. The predator tries to dig at the base of the run, hits the wire, and gives up.
