1. Negative Fan Reaction
If WWE and The Undertaker had been thinking about wrapping his career up against Brock Lesnar at WrestleMania 32, the tide of recent fan reaction against the idea may be changing their minds. People really aren't happy about the creative in The Undertaker Brock Lesnar feud. Fans have made their voices heard, be it in the arenas or on the internet, expressing disdain for The Undertaker's storyline. The dreams of his glorious retirement never involved low blows and repeated Brock Lesnar matches. Even the SummerSlam match, few fans really wanted it. Especially under the context of heel-ish Undertaker. The negative reactions to the storyline are reason enough to re-think any supposed imminent retirement. He should go at least another year, with the sort of creative that his legacy deserves, and an opponent who can really benefit from working with him.
