Yeah, that's my sense too, but it's not based on enough experience to be confident in my observations.
My wife and I made it clear to our son that we would much prefer he gain into a higher weight class rather than cut to find a spot. He will be a freshman next year and depending on how big he gets between now and the start of the season he may or may not have to compete for a starting slot (it's a small school with a small team). I'd prefer he be second string and grow as his body wants to grow. His uncle cut during high school and believes it stunted his growth. He never got any taller after he started cutting his sophomore year.
I am not saying cutting will stunt every person's growth. I do believe it probably stunts some people, especially if it is done during a time the body "wants" to be in a growth spurt. And those times are easy to identify in the rearview mirror, nigh on impossible to predict with any precision.
