I thought Caliendo looked small compared to David Carr (who looks big at 165 this year). Caliendo is very muscular but not tall/long limbed. I could see him slotting into 157 next year.
As a senior in HS, I wrestled 189 and bumped up to wrestled heavyweight for the team a handful of time throughout the year. I started the season around 200 and by midseason was weighing in around 186 after a hard practice. After +2 pounds for Christmas I had to weigh in over 191 to wrestle heavyweight. All you have to do is drink a gallon of water on the bus ride and you can put on 8 easy pounds of water weight to wrestle up at the next weight class haha!
