How do you make a 10 week schedule for 7 teams?

Divide the 10 teams into two divisions of five teams each.

Each team could play a division rival in the odd-number weeks.

For the even-number weeks, do a random draw of opponents from the other division. Since each team will not play the same non-division opponents, you should determine leaders on division record first.

If possible, the two division winners could play a championship game in the eighth week.
