Douby can play defense, can create his own shot, is long, quicker, more versatile offensively. House is just a spot-up shooter/screen shooter.
Stop overreacting and making ridiculous assumptions guys. Read up on him, and wait for things to play out with Bonzi. I expect he stays, and this isn't a factor in our main SG spot.
House, play defense? I have never seen him play any defense but get steals in pasisng lanes which anyone can do, and doesn't mean you're a good defender.
