i've looked at all this year's draft picks very closely and imo he would go at pick 15
As someone who's been watching and studying junior football live for years and years now(I'm not suggesting you don't), he'd be in my top 3 at the same age. Still a lot of development to come out of this years crop in the coming months however.
For mine Schache is certainly worth a top 10 pick. His debut year was very good for a young tall often taking the best defender. Admittedly, he has struggled this year in a side that's currently missing majority of it's midfield bar Beams and Zorko. He'd benefit a a great deal by being able to take the #2 defender. KPF's take a lot longer to develop.
