Describe the bug
When using the following example code from your README.md
`
from sportsipy.nba.teams import Teams

for team in Teams():
print(team.name)
schedule = team.schedule # Request the current team's schedule
for game in schedule:
print(game.date, game.points_scored, game.points_allowed)
`
It always returns:
The requested page returned a valid response, but no data could be found. Has the season begun, and is the data available on www.sports-reference.com?

The other classes seem to work fine.
