Zahid is a medal threat at 86 but certainly not a lock, Dake is on the wrong side of 30 and it took 17 years of complaining at Paris for him to get fired up enough to squeak out bronze before moving up two weights. The rest of 86 is unproven. I am highest on McEnally on the senior circuit but that's not the present and folkstyle wear & tear may do no favors.
74 has three u20 world champs and Carr/KOT and Carr/MM are already budding rivalries pushing each other. I'll take that for overall depth knowing any of those three could be dropped into the bracket and bring home a medal rather than one probable medal lock (Zahid) and drop-off. If Dake made 74 would probably have a different discussion but he didn't so we aren't.
Again, just my opinion and we know what opinions are like.
