10 Times WWE Failed To Replace Wrestlers
1. Lana (with Summer Rae)
The Difficult Second Act of Rusev and Lana's WWE run (before they revealed their real life engagement and had it retconned anyway), a split and feud with Dolph Ziggler and Summer Rae saw the 'Bulgarian Brute' and 'Ravishing Russian' split off in attempt to push both.
It failed on both counts.
Rusev's character looked rudderless when separated from the quiet pillar Lana had always been, especially when he replaced her with Summer Rae. The expectations were unfair on her too - Lana had played the role so impeccably that even as an intentional tribute act, Rae looked stuck in a dead end spot.
Meanwhile, the love square angle never even had a chance to get on the rails before it spun off them. Impossible to track and filled with Vince McMahon's worst impulses (Rusev was forced to make something of a skit with a giant fish one week, Lana was "americanised" with the the help of Dolph Ziggler the next), all four were in a far worse position on the card by the time the long and sorry story concluded.
