If you had enough people it seems that you could count the number of hits the defense robot scores on a offensive robot. You could count forced fumbles, you could count the amount of time that a defensive robot delays another robot. All of these metrics require close observation thou, and even if tabulated often will not be able to provide a complete view of a defensive robots capabilities, not to mention the difficulties in objectively collecting the information.

My advise would be to calculate the EOA (Estimated Offensive Abilities) of a robot based off of the number of tubes it scored each match, and then compare this to the number it scored when playing against different dedicated defensive robots. This would let you see if there can be a EDA (Estimated Defensive Abilities) calculated for defensive robots based off of how other robots predicted offensive scores compare to actual scores. This would of course require accurate records of every match for every robot including breakdowns and signal loses which would ruin the data.

This all seems like a lot of work considering the advantages it brings. It would seem unlikely that a team would pick a defensive robot for their first pick (unless it had extraordinarily defense) and in general by the time the second pick comes around the remaining robots are fairly easy to rank. Specifically at my regional (Utah) where only 29 teams are registered, this would be a waste of time since for the second pick there are so few teams remaining that the choices are usually obvious.
