Taders didn't submit a line-up. If he did he would have beat me. What do we do?

It's actually covered in the rules:

Roster must be submitted in full before kickoff of the first game. If no roster is submitted, the previous week’s roster will be used. If this occurs during the first week of the season, then a lineup will be submitted using the highest ranked players from the previous year.

I'm inbetween flights at the moment, but I will set the lineup when I get to my destination (around 6pm EST).

I totally forgot about that rule, I was actually going to say to give the win to my opponent since it was totally my fault (never give someone a sheet of paper stating the roster, the website, league name, team name, password, and how to submit a roster, and expect them to get it right )
