Eddie Guerrero (133 Days)
Yes. Jinder Mahal’s reign as WWE Champion just surpassed Eddie’s reign in terms of length. It’s barely a week ahead, but we all know Eddie isn’t getting another championship run. Still, 133 days is impressive.
He won the title from the monstrous Brock Lesnar at No Way Out after hitting him with a DDT onto the championship. He then remained champion for around 5 months. In that time period, he defended his title against the likes of Kurt Angle, Rey Mysterio, JBL, and Chavo Guerrero (not joking). He dropped it to JBL, who held the title for nearly 300 days. Lord, do not let Jinder be JBL 2.0.
