4. Brock Lesnar
You know how Brock Lesnar benefits from Seth Rollins' bad luck? Financially! The Beast has made it clear that his association with the WWE is very much one that's best for his business, and while he clearly loves stepping into the squared circle, the money associated with his cushy contract obviously helps to make it all the more enjoyable! Rumours point to a frantic Vince McMahon being willing to drive up to Brock's remote house with a truck full of cash to get him back on TV on a regular basis for the next couple of months to ensure that ratings don't slip any further, and it's easy to imagine this dominant former champion willing to say yes if the deal on the table suits him. This one also makes a lot of sense from a storyline perspective too. After all, Lesnar's rematch against Rollins for the WWE World Heavyweight Championship was cut short due to interference from The Undertaker, and now that he's dealt with The Deadman, it's logical that he would next set his sights on the title he was robbed of at this year's WrestleMania. The Beast's dominant run as Champion was great fun, and bringing that back in time for WrestleMania season definitely works.
