I wouldn't say it's a "narrative" - we're going to find real quick how well Sebolt kids do at the next level. Cullan, as the 1st generation Sebolt matriculator - came in injured and it has continued to hamper him. (although is a one tough SOB to continue to compete while hurt)
So now, it's Jesuroga, Kueter, Block, Arnold to a lesser degree and a bunch of other guys. Jesuroga is currently a casualty, Kueter is going to struggle unless he commits to full time wrestling or Iowa doesn't make a bowl game, Block SHOULD do well, and Arnold seems to have jumped levels since joining.
I think everyone on this board has high hopes for Iowa scholastic wrestling, SWA's continued success and these guys becoming AAs and Champs for Iowa.
But just like you said, it can be said of many clubs and many sports. That doesn't make it ok, and that doesn't make it NOT a worry.
