这里是YAHOO 规则:

In a Head-to-Head League, your team will square off in a weekly matchup against another manager's to see who can compile the best stats across a number of different categories.

A new weekly matchup begins every Monday and will consist of a set number of games based on your league's statistical categories. Each stat category counts as one game, with the win going to the team that finishes the week with the highest total in that category (the cumulative total after each Sunday's games).

请看: your team will square off in a weekly matchup ,每队阵容是每周固定的.

A new weekly matchup begins every Monday 同样说是WEEKLY.

我们LEAGUE允许每天改阵容,但每天改动ALL APPLY TO THE COMING WEEK.就想SALARY CAP FOOTBALL.

当然.改动是必要的, 打球场次多的有ADVANTAGE.
