How many times do you see a tie match, and kids laying on bottom stalling waiting to put out a burst to try to escape late and win? I do love it when it backfires and they get turned to lose.
Riding time would get rid of that crap, and force the wrestlers to push the pace.
IMO we see more stalling these days from the neutral position than top or bottom. I believe the refs do a much better job of calling stalling on top or bottom than years ago. I don't know if riding time would improve it more or not. I do have a deep appreciation for wrestlers able to ride effectively without stalling. I find college wrestling kind of boring in comparison to high school, but again I'm not sure if that has to do with riding time or not. It has never appeared to me that the wrestlers give any attention to the riding clock and it seems, rightly or not, that the same guy would have won the match regardless of the riding time.
