Well the stable can't be invincible. At least it's not like Evolution where a mere 4 guys were bullying a roster of 30+ wrestlers (Or even Shield that 3 guys has the 30+ man roster terrified
). Eventually the numbers game plays a factor and it makes it more believable. A&E can't out-muscle the entire roster so they use low-handed techniques, and occasionally get beatdown themselves.
I haven't seen any members of A&E get 'buried' like many discussions suggest. Getting buried would be like a squash match. Like when Shaemus destoryed Daniel Bryan in 2-minutes on RAW with 100% offense compared to Daniel's 0% offense. Complete and utter squash. Then again at Wrestlemania for the Heavyweight Championship. I've seen nothing like that in these A&E defeats.
Sure they may lose, but who cares if they lose a 'wrestling match' they are anarchists
. Losing a regulation and orderly match means nothing to them so long as they accomplish their goals (Taking out Sting and Angle). Unfortunately TNA is getting away from that and started to make A&E care about matches & titles, when they shouldn't.
