You actually believe that the group is more likely to split before recruiting other superstars?
I actually believe a couple will try to join the shield before they split up. I really like this new side to things, having the possibility of disruption.
I think its pretty obvious Ambrose is the leader and the more charismatic of the three.
There are to me a few ways things could go.
You could split them up eventually with the team starting to feel differently about injustice.
You could have others join and for the group to become bigger which means more people to start disagreeing with actions taken. For example, Seth, Reigns and one of the new guys go down to put a beat down on someone. Ambrose and another new member disagree causing a divide.
Or a new member could join, this member could act in line with the group but slowly start to split them up over time after he has gained their trust.... like a mole within the group.
A Diva could cause a rift between them. Start dating say Rollins, but be seeing Ambrose behind his back.
However, what about the others oustide of the shield?
What happens if for example Team Hell No were to turn around and say, ok, Shield, maybe you are right. We do need to work as a team, become united, become what the Shield want them to be.
Would there be a situation where they come on a mic live, call out the shield and say, we have learnt our lesson. Would this stop the shields interference? Is this a way to go to open up storylines?
Endless possibilities
