As much as I love Dean, I just can't buy him as a face champion. Just not right now. He would have to somehow turn heel. Or turn Reigns heel and slap the title back on him. Then make Ambrose chase Reigns to give Reigns the heat he's already getting anyway. Then when Ambrose takes the title off Reigns, we should have Rollins back in the fold to give us that Triple Threat match we all so desperately want.
My bit of fantasy booking includes:
Dean beats HHH for title at Mania.(Huge 'feel-good' moment).
Roman beats Taker to huge boos in Texas.
Roman gets to face Dean on Post-Mania RAW, turns heel and goes corporate and to top it off, defeats Dean for the title.
