#7 and #6 Mike and Maria Kanellis

It actually surprised me that WWE signed these two a couple years ago. Sure, Maria was a big hit on the indies in ROH and NJPW, but Mike was usually nothing more than a decent tag team wrestler or mid-card guy at best.
There was a reason he never received a main-event run in ROH or Impact Wrestling when both were there. Think of the B+ player storylines only with a C instead of a B.

Maria actually seemed to get more from their deal with Impact as she became the tyrannical head of the Knockouts Division.
They probably think of themselves as big deals, but I was actually surprised that WWE thought enough of the duo to sign them to contracts.
The brand split was in full swing and WWE was trying to sign up as much talent as possible so that the competition couldn't.
But since they had a run in practically every other big promotion, where else would they have gone?
They may or may not have requested their releases earlier in the year, but I cannot see them sticking around once their deals expire. Perhaps going back to one of their prior homes will be better for them since they haven't been booked as world-beaters.
