What's with NHL 12's save system?

So I start a new season, play a few games and notice there are like 5 different save files in my NHL 12 folder. Does it create a new save after each and every game meaning i have to go and clear out the folder to keep from having 82 save files throughout the season? Seems a little weird.

I know it's a strange way to auto save games,but I think a good part of reasoning for this is because if you were interupted during game play and had to shut down your console or power outage,it will save on one file after you've made a trade or finnishing a game,while on another file if you have decided to go back on a trade you thought was bad or power outage,etc,you can alway's go back.Get it.No problem.If you have five,that's really strange.I only have three save files,and I play Be A GM.I hope my input helped.Does not mean my reason is the correct,it's just the best guess I could make.Good Gaming.
