Player Lines and History
Arena reserves the right to add, edit, or remove players from the Picks sheet at any time, for any reason. Often times, the line (player projection number) projections will change throughout the week. Once an entry is submitted, that is the number at which your entry will be locked and graded by.
For example, if you submit an entry that contains a player's line (stat projection) at 25.5 points, and the following day that player's line is now at 30.5 points, your pick will be graded on the 25.5 number. In short, you are locked at the line at the time of your submission.
Stats (ie Props) depend on the sport. You can view all available props in-app for each sport. Arena will show single props such as passing yards, goals, points, rebounds, assists, etc. Combination props include points + rebounds, rushing yards + receiving yards, etc. Check the exact sport in-app for the available props.
