The brick is a good example of this, I've see many example. A classic case: A takes down B and been is flat on the mat clearly going to be on bottom for 30+ sec, maybe thru end of period. Coach B throws a brick to question that the takedown was called early. Now even if B loses the case he is still going to get a restart so good chance of escape thus no/minimum riding time. B may win the challenge even though A would've got the takedow a couple seconds later, thus no TD back to neutral. Its also a good lung time out brick, that flat wrestler wasn't getting out due to lung issue but give him a two minute break and different story. Questing locked hands also works. Lot of coaches using the strategic brick.
My view: the current rules are working fine but I hate the brick.
