The underdog role works.
It worked with Rey, and it will get Kallisto over even more.
Not sure why people are being salty about it.
Do people expect Kallisto to dominate Del Rio or something? Seriously?
Someone that they can slot into the WWE title scene if they need to or anywhere else?
Kalisto isn't an underdog. He is a lucky bastard that couldn't win with his finisher, twice.
If you want to see a good underdog win, go watch Mania 30. That's how you book an underdog overcoming the odds.
