You can take some measurement related to the sport and then model it over time.

Anything recorded could be plotted. Say if you were modeling American college football wins (yes/no), many large programs play smaller schools early in the season. So you would imagine to predict wins early in the season based on prior year's data since playing smaller schools is a 'seasonal' pattern.

Why don't use a regression model instead of time series analisy?

Because OLS regression assumes independence of observations over time and you don't have that type of data.
