The WildCat

There is nothing more I hate in football then Wildcat formation. My question is why is it any different then just running the ball? Why is it so hard for defenses to pick up? It would seem that not knowing whether or not an offense was going to pass or run would be more confusing then wondering where a player might run. I just don't get it. Maybe I'm ignorant as I have never actually played organized football. All in all, I hate watching, listening, and hearing the name Wildcat when enjoying a relaxing Sunday on the couch.
