We had a theme like this is a previous WIS Championship round 2. The cap was lower, and it was a five round draft instead of six (we drafted two franchises and three seasons, so 3 x 2 = 6 teams). The other major differences is that franchises were allowed to be taken four times instead of three. I think this version of the theme is a lot tougher since the popular franchises and the best seasons will start to become scarce more quickly.
So if you grab two franchises early, you might not get the seasons you anticipated. If you go with a season early, the franchise you had in mind might be unavailable. Flexibility is the key. You'll need to anticipate the worst, then adjust.
