The is no reason for the Streak to end at all... at all. Losing the Streak would just be a way of saying...somebody was more important, so you lost. Even if he insisted on losing, greater heads should prevail.
What else does he have over HBK, Bret, Austin, Rock, Hogan, HHH and Cena but the Streak? He outlasted them all and I've never heard one bad word said about him, ever.
IF it were to end, it should be by a lifer. I'm talking Chris Jericho, Daniel Bryan or John Cena. Silly, I get it, but so are some of the cats you guys are suggesting to end it. (No offense, I realize we are all pulling at straws, hypothetical if you will)
The ender should love this business more than you or I. Jericho, Bryan and Cena epitomize this, though I favor Jericho or Bryan who would out-wrestle Taker to a win. Passion and not $ should win out in this scenario
