The Good Brothers

Like Harper, the Good Brothers have gone on record as looking at the pastures outside of WWE. They decided not to re-sign new deals with the company and will see their current contracts expire towards the Fall of this year.
Unlike Harper, however, they have been used on TV here and there. They had a few matches on Raw in May and have been seen chasing down the 24/7 Champion in a few segments.
While neither man will likely win that title, it gets them on TV and doesn't paint them as bad as not being put on Raw or SmackDown does. A lot of people think that they'll sign with AEW due to the thought that the promotion will better feature its tag team division, but they have a lot of history in New Japan Pro Wrestling. They are definitely leaving the WWE but where they will eventually sign isn't as clear.
