He needs to rise above jorts and slip into some trunks. Personal opinion.
I think Cena should ditch the jorts and switch to trunks too. But I also think he should keep the t-shirts, hats and wristbands. Like color coordinate them with his trunks. He can have a U Can't See Me, Rise Above Hate, Never Give Up, or whatever slogan on the crotch/butt of his tights.
