Step 2: Click on the “Trade Center”
Step 3: This will bring you to 3 options “Trade block”, “Upgrade Position”, or “Manual Trade”. Clicking trade block will show you players that other teams are looking to trade. Upgrade position will sort the players by the positions your team needs. Manual trade you are free to scroll and look through any player on any team. Select which of the 3 you would like to do.
Step 4: Find a player you are interested in and select them by pressing A/X, this will add them to the trade.
Step 5: Press the start button to “advance”
Step 6: You will have two options of whether you wish to offer a player or one of your draft picks select which you would like to do.
