I don't believe that he will be at quite the same size disadvantage that Beau was. Beau has subsequently said that he could have made 133 that year if he had to (there was no spot for him there, either, obviously), which is why he originally insisted on being a 141 and challenging Lee, which we mistook for a bit of arrogance. He was truly too small for 149 but did it anyway eventually.Is Kasak that small though? According to Cael, he had been working hard to get to 141. After Sr Nationals he can build himself back up.
Lehigh was one match. He has 2 more competition dates, let's see how he does.
With that said, if there is a weakness I've seen in Kasak (from admittedly limited exposure to his wrestling), it's that he can sometimes be overpowered and horsed around a little. That's not a good sign for a true freshman wrestling up a weight, but he is very talented, so it's not something he can't overcome, either.
As I said above, I'd prefer to see him go than transfer Gomez in (not that I even think that is a possibility, but it is the topic du jour here...). I think that they are both capable of a mid-AA finish, with the difference being that Kasak would be exciting to watch as a true freshman whereas Gomez would be a small underachievement.
