The only way that comes to mind is by unsharing the spreadsheet and sending a private link directly to you. Unfortunately, this requires that you send me your email/Google addresses via PM, and posting image recaps here on the forum for those who don't have access. I'll leave it as is for now, but should it get ruined again I'll have to do it that way.
TL : DR - I'll be sending out PMs to all persons who have teams in the League within the next 24 hours.
