Dake's streak was 77. 5-0 at NCAAs his sophomore year, then 35-0 and 37-0.
Yianni is sitting at 75 straight (18-0 since losing to Eierman, then 29-0 and 28-0). If he wrestles the whole Cornell schedule (he's likely to skip CKLV due to the World Cup), he'd end up with 106 straight wins (and a career of 125-1). Add in his HS streak, and he will have gone 335-1 since his last loss in HS.
