4: Daniel Bryan
Daniel Bryan has not been around the WWE Championship picture since dropping the belt to Kofi Kingston at WrestleMania and given that he is now set to finally turn face again, now would be the perfect time to elevate him back up the card.
Bryan and Lesnar put on an excellent match at last year's Survivor Series and an extended series of matches between the two could really help get the best out of both of the competitors.
Bryan got over in the WWE as their ultimate underdog and the company needs to turn back to that kind of booking if they want him to rise to the top of the company again. SmackDown on Fox is without a clear babyface to promote the brand who the fans are genuinely behind and Daniel Bryan could present them with that option if they were to finally book him correctly.
The feud between the two men could be booked in a way that was similar to their match at Survivor Series, with Bryan valiantly attempting to overcome the odds but just falling short. Lesnar it as his best when he is working with men like Bryan and this one could be great for everyone involved.
