The Big Bash League has produced plenty of memorable seasons, and I think one of the most interesting things about it is how quickly a team's fortunes can change from one year to the next. Some franchises have built a strong record of success, while others have had to wait a long time for another title. What matters most in the BBL: consistent performances throughout the season, experienced players delivering in the playoffs, or having a few match-winners who can turn a game around in a couple of overs?
