Except that he's never going to get into a college wrestling program without wrestling in high school.
When I said if you can get in a college program "later on" I meant wrestle through HS and work to get in a college program. Sorry if I didn't make myself clear enough.
I have done BJJ and Judo. I think if I walked onto a college wrestling team I could try out and do pretty well (although it would be pretty tempting to armbar someone).
