I can see Vince seeing Heel Cena/Roman the same way as the Stinger. Remember when he said "He's a special attraction, he can't appear all the time or else he won't be special any more". Yeah no shit
But Cena draws as a heel, whenever he's positioned as such it's worked spectacularly. Fans flocked to Summerslam 2014 to watch him eat that Lesnar asswhoopin'. Rock vs Cena drew on its own because of that. Summerslam 2013, as Daniel Bryan got his big break. MITB 2011, need I say more? And even the Cena Open Challenges this year he was essentially the " heel" from a sports sense. All these things were special because of it, because Cena was the best heel of this generation... Maybe that's why they think creating a new Cena isn't the worst thing in the world, but... We'll see how that works, with a bag of pretzels nearby to sit and watch the dumpster light on fire.
