The par terre deficiencies greatly disturb me.
Brooks had a gut wrench locked up in the semi and chose to put about a 1/16 effort into scoring with it. Those points could have made a difference. Geno, Taha, Saduleev, etc would not have hesitated to score there.
I think one of the reasons there wasn’t a lot of scoring action in the 57 kg final is that both guys had a strong respect for how ugly the shore could get if they were taken down. You don’t want Higuchi to lick up an easy lace or guy, because they WILL score with it… or at least try to.
