Yeah your other games will of course be counted...
I've kind of slacked off posting the rules like I used to (I did do week 1 scoring to provide an example) but honestly it's because there aren't many and they all are pretty obvious. The most basic one of all is that you have to pick the winner of each game before that game starts. That means the Thursday night game must be picked before the Thursday night game kicks off. Same for the Sunday games and Monday night game...
It is not unusual for someone to make their Thursday pick then come back later for all the rest.
I know this is your first year. As I said before, I was very polite and even included a heart in my post.
Anyways, you won week 1 and I doubt one game in week 2 is going to make or break your season.
