All I see is that it only took 48 points to finish in first place. It must be an ultra-competitive league.
In essence, the OP lost a coin flip at the crucial moment. It would have made huge headlines in the real world, if the second place team came roaring back in the final few games for a showdown in the final game of the season.
Indeed, it must have been very disappointing for the losing team, but this is very very normal in the real world. Last-minute losses happen all the time.
