OT - American football, because I like the strategy of the game plan, the tactics employed to get there. The way a play unfolds.
Every play is a potential touchdown - unless the perfect defensive play is called and executed. Then, it is a potential touchdown the other way.
The Immaculate Reception. The Drive. The Fumble. The Comeback. The Tackle.
More than one American SF member knows what all five of these plays were.
