#3 One last title run
While his most recent run as Intercontinental Champion was underwhelming, to say the least, Ambrose has been an excellent servant to the WWE over the last 6 years, and one last run with a mid-card title and a feel-good passing of the torch moment to see out his time in the company would be a nice way to draw in his time in the WWE to a close.
It is certainly difficult to see what title belt Ambrose could win in the coming months, but if the WWE really wanted to make this happen, and send Ambrose out on a high, then they could easily do it.
