According to F4WOnline.com, the reason why WWE had The Miz come out during the Titus O'Neil match on Raw this week and cut a quick, "angry" promo is because it will likely be setting The Miz up for a tag team with Dolph Ziggler.
WWE planted the seeds for the team with Ziggler as well, when he cut a backstage promo for the WWE App during which he vented about not being used properly in WWE. The idea behind the Miz/Ziggler tag team is they will be "disgruntled angry man" wrestlers who are upset with not getting the push they deserve.
