Del Rio is a solid wrestler, Top 10 in the company. His gimmick though is stale. You can see Del Rio is stressed with his character, because it's not who he is. Interview wise out of character, you can see how Charismatic Del Rio is. If I read correctly, prior to Del Rio coming into WWE he was a primary Babyface talent. Although with the Richman gimmick it kills the mood, along with his Crossarm breaker; a secondary move, one that shouldn't be a finisher.
Seeing Del Rio, I can see he would work well with a Latin Lover type of deal.
