I like the rules and the myriad of options our wrestlers have to score. Tilts are exciting, pins are exciting, Jordan Burroughs double legging the same guy 12 times is exciting.
A pin is the most dominant form of victory we would all agree, no? There is often a wide disparity in the two wrestlers abilities when a pin occurs. When two wrestlers of similar ability(or a slight mismatch) wrestle it is very difficult to pin someone who is close to you in ability, so you must learn how to win without pinning. Scoring points with take downs and turns then become the next resort.
Really by your logic choosing down in the second or third period would be stalling since that would be voluntarily putting yourself in the position furthest from pinning. It really doesn't make that much sense to me.
