HeymanHustler
The One...The Only...and The Best
Yeah, like everyone else has said, it would be tough to turn Taker even if they tried because everyone loves The Streak. Not to mention pointless. He only works a month out of the year these days. Comes in a month before WrestleMania to hype the match up, works the match, and then (if he does the same thing he did last year Post-WrestleMania season) he works a couple matches for a couple weeks before he's written off TV.
More importantly, he doesn't have to always face a heel at Mania. At WM25, HBK was a tweener at best and a year later, he was a face who had just reached his breaking point after becoming obsessed with The Streak. HHH was face during WM 27 and 28. At 29, Punk was the first full blown heel to challenge The Streak since Edge at WM24. Young guys like Reigns or Bryan can still get over in face vs face confrontations with Undertaker. In fact, they'd get over more as faces than heels. All they'd have to do is get an arm raise or a hand shake from Taker following the match after a losing effort and their career will be elevated to whole new heights after that. Like when Taker raised Jeff Hardy's arm as a mutual respect thing after he beat Jeff in that ladder match for the WWE Championship back in 2002.
