Zone history

I think it's possible to reconstruct a lot of Zooooooone fantasy history from a couple pages. All the Yahoo league scores can be found in your profiles here: http://profiles.sports.yahoo.com/. The CBS sports one might be tougher, but my league keeps this info, so it's possible. The help mentions a league record book and includes this:

Commissioner Only Features:

Add New Record - Located at the bottom of the Standings/Record Book page. Use this feature to create records that you can keep track of manually. They will show up along with all the otherrecords in the record book page. As with all commissioner-edited records, these will appear on the report in red text.

Edit - Allows you to change the values of the Record Book page. When you override a record, the system will continue to calculate the actual record based on the information it gets. So if you change your mind, you can just delete the override and the original record will then appear. Commissioner edited records will appear on the report in red.

* If you edit a Record Book entry that was created with the "Add New Record Feature," the previous data will be overwritten by your new entry and will not be recoverable
