who knows how kids change from year to year, but simply looking at last years state placers, you have several prospects for that 55-58 pound range.
In no particular order:
Hood - Louisburg
Roy - Paola
McKinney - Paola
The Brown Bros. - Osawatomie
Erpelding - Atchison
C. Seaton - Bonner
Lohman - Turner
Wrestler - Chanute
Add others like Thoele - Linn Co., Lynch - Sunflower, and I am sure there are many others I am forgetting. Not many 10 year olds are still this light. Most of the state placers from district 1 are back. I am sure there is alot from the rest of the state as well but you asked specifically about Dist. 1.
