I don't see much of a return on investment in this.

While you sit there "blocking" the trackball: a. you are not scoring points. b. the other alliance can still be doing laps without the one of their trackballs and continuing to score points, and c. Contact in the bumper zone is still allowed, so long as it's not egregious behavior.

If a robot from the other alliance is trying to push my trackball into a 135^o corner, I'd tell my drivers to just start pushing their robot. No high speed ramming or egregious behavior, just solid bumper-to-bumper contact. With the covers on the trackballs being so slippery, something will give, and I doubt that trackball will stay cornered for very long.

Now if there were 90^o corners on the playing field, this strategy would be much more viable. But with the current field, I can't see it working for very long against a robot with a decent driver and drive train.
