Would you buy Zack Ryder joining the Shield?
If you look at the Shield's gimmick - IE> Shield against injustice - you would have to say that nobody was treated worse or more unjustly than ZR in 2012 - from his momentum being cut at the legs to being a sidekick in terrible story-lines.
Would you buy Zack beating someone in the ring - then the Shield surrounding him - looking like a beatdown - then suddenly he kneels, they shave his head, burn his merch and he proclaims that he joins Shield because of the injustices done towards him.
Putting ZR in a group with also address his shortcomings - with Ambrose doing the heavy lifting on promo work.
Obviously the current ZR character will go in the dustbin along with the merch - making way for a new, more serious Ryder.
Or...is making ZR in any way credible a ship that has sailed? Should the Shield only stay at 3 members?
