The Brian Kendrick
The Brian Kendrick was clearly brought in to 205 Live in order to be a stable veteran hand that could be plugged in wherever needed. His job is to share his experience with others, and make them look good. There is no reason that he cannot do the same on SmackDown Live.
He knows his character inside out, and would make a fine addition to the mid-card, floating around wherever he is needed.
The WWE showed faith in him before when 205 Live was in its infancy; he was trusted with the championship when the TJP experiment failed miserably, and vindicated the company's faith in him.
Brian Kendrick is not going to be the star of the show; he will be a supporting player, but that is an important role, and one that he would excel in.
