Actually with the new PDP you can get current draws for each power output. So as long as each motor controller is wired 1:1 with a power output on the PDP (which it should be according to 2015 rules), you can get the current draw from each motor.

The Power Distribution Panel (PDP) is the latest DC power interface for competition robotics. The PDP uses CAN to connect directly to the roboRIO and allows for individual current monitoring on each channel.
