When Cena faced off with Lesnar at Backlash 2003, his home state cheered for him over Lesnar most of the match. He started getting slick with the written raps for the rest of the year...got cheered hard against Mysterio at one point. Got heat but the cheers were getting overwhelming. He faced off with Angle and they were doing that Let's go Angle/Cena shyt. He faced off with Taker and the crowd wouldn't cheer against Taker...did the US title thing with Eddie and the crowd stayed with Eddie because his lying, cheating, and stealing gimmick was on FIRE fall of 2003.
At Survivor Series 03, it was Team Angle vs Team Lesnar. Cena was a main plot and was recruited but went Team Angle and has been face ever since. He went from losing most of his top matches as heel to becoming almost unstoppable..winning as much as Shelton was on Raw as IC Champion when he got the US title. He did a job for Carlito's debut but left television to film the Marine..came back for Survivor Series 04 on Team Guerrero and crushed the Carlito sidekick "Jesus" who tried to kill him or some weird $hit. Lost the Rumble to Batista in a face off but was still pushed on top towards JBL(who had gotten by Eddie, Taker, Angle, and Booker over the last half year).
