No, he should adapt his character so that he can effectively function as a face. Cena is fully aware that more than 50% of the crowd boo him, he has acknowledged it for years, and the fact that he continues to do nothing about it and just spouts the same old crap despite being aware that the people are sick of it is inexcusable.
Bull, many top guys would LOVE to chnage they charcther but guess what? they CANT.
You can say this all you want but its not true
Orton WANTS to be a face
Taker WANTed someone to beat him at WM
#1 even if he did "chnage" it wont chnage anything pepole will still boo him, not cause it sucks or anything but becuse its what they are "sopoused to do"
#2 what could he chnage to that would make pepole not boo him? thats right nothing becuse it has nothing to do with "Stale" and evreything to do with "oh chants!"
