We use 1 sheet per team, and I LOVE our new sheets. Because all 12 matches (usually 7-10 when making a pick list) are on the same sheet, we use the sheets to help sort teams. The new sheet makes this so much easier than the old sheets (thank you 3929). You should be able to see a nice evolution of our single sheet system.
As far as what do I do with old sheets? I tend to save them. We use them time from time when doing stats relative to games, or week 1 vs. week X or OPR vs. "real" scoring or why does team X seem to win every match or....
Just be very careful not to loose a sheet.
