Haha, like that pussy who slapped some guy on the cheek and got ejected? If you're gonna get ejected at least punch him in the face or something and make it worth it, or just have a bit of control and not hit them in the first place. Soccer is pretty boring to watch, and you exaggerate the amount of thinking way too much. It's the same amount of thinking as in basketball or hockey.
FYI, football doesn't take as much thinking as other sports like soccer or basketball for some positions, but it's a game of pure athleticism. When you have some of the best athletes in sports, theres no way you can get bored when they play the game at such a high speed.
