Out of all the names on that list, Roman Reigns. It would have been too early for him, but it would have been believable and also a probable way to have Ambrose and Rollins turn on him out of jealousy if they had wanted to take The Shield breakup in that direction. Bray Wyatt should have been an option in this poll, too (well, I guess technically he was, if you voted for 'Other'), even though I wouldn't have voted for him regardless. For some reason, "Bray Wyatt - Streak Killer" just doesn't feel right.
If Randy Orton at this stage in his career was as young and motivated as he was back during Wrestlemania 21 (where he faced Taker) or 22 back when he was the "Legend Killer" and had his whole career ahead of him and had never faced Taker at a Mania ever before, then he would have been the absolute perfect choice. And just to do even more fantasy booking, if Goldberg had never existed in WCW (or in WWE in 2003-04) and was a new fresh face that had only debuted in WWE just recently with an undefeated streak of his own, and if we pretend that Goldberg is exactly the same as he was back then (same music, entrance, finishing moves, overness, crowd anticipation) and he faces off with Undertaker at Wrestlemania, that would have been epic and the perfect ideal scenario to see the streak come to an end.
