Also I feel that when Cena does end up going heel he will eventually reunite with Barret to form a sort of Nexus 2.0 where Barret convinces Cena he did a ton with Nexus and the potential they had went wasted due to Cena being unwilling to work together but things are different now. Makes room for them to be dominant and still provide wiggle room for Cena to go without looking bad when they are beat.
