I rarely watch sports events live. Each sport has a fairly predictable timeline. For example, an NFL game is about 3.5 hours of clock time for what's an hour long game (skipping clock stoppage and half-time). So just start watching 2.5 hours after kickoff and you catch up with real time by the end of the game.
