Drive Team Speculation

Frank Merrick just posted a new blog on FIRST: https://www.firstinspires.org/robotics/frc/blog/first-championship-allocation-for-districts-and-first-power-up-buttons

And in the blog there was the new drive team buttons design picture.

Last year there was 6 buttons; 4 for drive team, 1 coach and 1 safety

This year there is only 5; 3 drive team, 1 technician and 1 coach.

2016-2017:

2017-2018:

So…thoughts
-No human player?
-Technician…pit captain or SOMETHING TO NOTICE?!
-No safety or is that replaced by technician?
