So I did get this thing (hopefully) working in time, but just barely! The main landing page will be for showing the current standings. To make your picks, there is a button near the top to "Add picks". That entire page will be the form, with a Save button at the bottom. You don't have to pick a winner for all games, but one you do, you can't undo it. You can change your pick, or the spread, any time until the deadline, but you can't remove your pick.

The deadline to submit will be as soon as the first game of the week is scheduled to start.
The standings are calculated each time a new score is added. As soon as I have data for all of the next week's games, I'll update the form for those.
Also, I didn't have much of a chance to spend a lot of time testing so if you come across any errors, please let me know ASAP so I can try to get them fixed. Screenshots are always helpful when reporting errors, too!
Good luck y'all!
