10 WWE Superstars With The Most To Gain At WrestleMania 31

3. Rusev

There aren't many people on the WWE roster going into WrestleMania with as much momentum as Rusev. He's on a really big winning streak, has improved a tremendous amount in the ring and on the mic, and is fresh off of defeating John Cena by submission. He has an incredible amount to gain at Mania. Think of what another win over Cena would do, especially in something like a Last Man Standing Match. He would be the United States Champion, but you might as well put him right into the main event. The man has come out of nowhere to become someone who probably should be in the WWE World Title picture in 2015. When he debuted on the main roster, he was just another "hoss" that moved awkwardly in the ring and couldn't cut a promo. He can't relax now. He has to keep improving, and keep on participating in entertaining matches. This could be his best shot to move out of the midcard.
