I think the OP has the more realistic scenario in mind where you take an under performing robot and convert it to goalie duty. If you have the capability to program a robot to intercept shots, you should probably be programming it on offense.

If you happen to have a robot on your alliance that cannot score offensively, and can mount an 8' pole to it and stick a corner in the goalie zone in front of your opponent it might have some value. Especially since the average robot will be probably just drive forward and shoot, or even the ones looking for hot goals will be just turning left/right off the center position to shoot.

This would be especially valuable if a top tier robot was able to shoot its own hot ball in < 5 seconds, then intake the goalie's ball and shoot into the other goal. However, that seems like like a tall order.

Regardless (though I expect a clarification allowing the offense last touch), not all field positions are equal. I think placing a disabled robot dead center, as far at as you can while touching the goalie line, and a jury-rigged blocking pole has some value for an essentially very low value team mate. Even if the offense can move, they might not be able to recalculate shot distance to compensate for left/right goals being different distances as they try to shoot the hot one.
