We can go about this a couple ways.
Posting rules: All plays will be submitted through a google form to be set up for that purpose.
1) Enter your picks and have them fully visable throughout the contest and being penalized for duplicating his opponent's plays. (Duplicates graded a Push if outcome is a Win, a Loss remaining a Loss).
OR..
2) All plays would be hidden until after the deadline with obviously no infraction incurred should there be similar plays between the two opponents. I am recommending a 7pm ET deadline but this is up for debate. My plan would be to release the picks at the 7pm deadline and copy those plays to a post in the thread. Once the final game of the night has tipped off, I would post lines for the following day and reset the spreadsheet to hide subsequent picks for the next day.
