Should the celtics draft Kevin Durant or Greg Oden, or someone else?

I personally think Durant fits the system best. They need a pure 3pt shooter and Durant is that. He can also take any defender to the basket. He is basically Kevin garnett with a better shot. Oden doesnt show enough potential on the offensive end. The celtics could use a dominant big man. If they do not end up getting either, they should go for Acie Law or Brandon Rush.......What do you think?
