It's true, i can't see where Brock fits in at Wrestlemania at the moment (unless Triple Threat). I originally thought they would have Brock win the rumble as and Reigns as the champion.... essentially reverse from last year.
However i think TLC sown the seeds of a HHH v Reigns rivalry, and i really can't see them not having a pay off from Reigns destroying HHH last night, and that's a match they won't give away at Royal Rumble or Fastlane.
I think the only way HHH vs Reigns won't happen is if HHH vs The Rock happens, which apparently was the plan but The Rock couldn't get cleared by his insurers. HHH comes back to destroy Reigns, Rock makes the save and sets up that match for Wrestlemania. Leaving the way for Reigns vs Lesnar 2.
How ever right now, i can't see it not being HHH vs Reigns.
Love to see Lesnar vs Owens, but it doesn't make sense. They will have to give Owens a super build between now and then (although what he did last night teased that) but even if they do, it'll be wasted if he loses to Lesnar.
