Let's look at the options.
Cena - Major opportunity to make a big moment at Mania by running a two man power trip between two of the biggest WWE stars who turned Hollywood.
Would make sense because of Cena's desperation (all he does is lose nowadays) to win number 17. The press conference also made him say the infamous best for business line which was very heel like. Also his prior history with Rock comes to play.
Punk - Works if the 'favor' factors into the decision of teaming up with Rock. Heyman would have to be cahoots with Rock to turn on Roman also. Which in turn leads to Rock and Roman next year. So for future storyline purposes this could be the best option.
Rollins - Yesterday's segment made this a stronger case than it has any right to be.
I personally wouldn't go with it because we've seen Rollins in a major corporate stooge role in the Authoriry. So that's 'been there done that' status.
Drew - Definitely a strong case. You can tie in the Rock resigning Drew and awarding him a sword for his efforts. Also a way for Drew to corrupt the Bloodline from withing since he has struggled to take them down on his own. Stronger option than most but wouldn't make for a popular choice.
Logan - A hat on a hat. Breh already the biggest heel in the company. So this is a hard no.
Priest - Best option of them all
