In the post there is a picture of the new drive team buttons for 2017, if you look closely you will notice that there are 4 drive team buttons and another for the drive coach. Could this be one of the hints for this year's game, will there be an additional drive team member on the field.
This is something that could open up some cool possibilities with the game, as long as it doesn't end up with human players scoring more than robots do, ala Lunacy in 2009.
