I'm not sure, but if it was an open league I think the answer is no.
If it was a theme league, and the theme is still around and the commish has set up the league to link to past seasons, then you could either join again and look at those past seasons, or send a sitemail to the commish and ask him to copy and paste your lineup from that past season.
I wish WIS would make it easier for us to look at old teams. (I know there's a way involving downloading zipper files and decompression disks and whatnot, but some of us aren't Russian hackers and will never suss it out.)
