The hands down sparring is just a response to the particular rules of Olympic TKD sparring. So is the way that both competitors were sparring. It's just a game, not a fight. The competitor that understands the rules the best and develops their skills within that paradigm is the one that is going to be the most successful.
With that being said, yes it was a boring match, but there was a major mental game going on between the two fighters. Lots of working for position and trying to out fake the other fighter. Anyway, I don't think you can totally dismiss these two...
I wouldn't dismiss them of course but I like my fighting more gutsy, more in yer face lol! it's a bit dainty for me
