Will the Raiders make the playoffs?

I know this is a very big push but it is possible. The Raiders last year were extremely bad in run defense, they got McClain and Houston to stop the run. They got Jason Campbell from the Redskins which is an extremely big upgrade from Russel. I think the Raiders can win 8-9 games next season if they have no big injuries. they have an easier schedule and their division is very weak. The broncos rebuilding and the Cheifs not doing that great i see the Raiders as the 2nd best team in the division. The chargers arent as good as a couple of years ago. So heres the question...Can the Raiders possibly make the playoffs next year?
