Lonvg time lurker here, 1st time poster, hope donvt embarass myself much.
Cena winning was the absolute right decision. He is the undisputed #1 guy in the promotion, and he had come off a lot of jobs, jobs that could make the kids lose some faith in him(similar to how I did when Hogan jobbed to Warrior @ Mania 6(bad bad decision in retrospect huh?). He was coming directly off a clean as a sheet job to The Rock in the most watched Wrestlemania of all time(still don't get that booking, but I'm hoping they do a trilogy, with John winning 2-1). not to mention putting over Punk all summer, and making a star and a clearly defined #1 face to the fans, and creating a foil for himself for years to come.
Basically if Lesnar was in for a REAL contracted year like Goldberg in '03(don't get me started on the stop/go booking of him) then yeah, the "Outsider" Lesnar needed the win. But as it is Lesnar is the modern day Abdullah the Butcher. Comes into the terroritory to boost buys/viewership by working top guys a few times a year, but is never positioned as THE top guy.
Cena will be main eventing 1 million+ buy Manias and breaking merchandise records for the next decade, while Lesnar will be doing shoot interviews cutting down WWE. I just hope hope hope they use Lesnars Mania program and all his dates to put over Bryan or Punk. Or if they must, a faux MMA exhibition with Taker. Please no H' rematch. Loved the Summerslam match, but only as a 1 off deal.
