Does he realize that homeschooling and seeing his friends are not mutually exclusive? Could he play soccer while being homeschooled? Around here I know there isn't even a team associated with school until 7th grade and then I believe you can still join a league team instead of the school team. It's very hard for kids who are the *thick* of school culture to see beyond it. He may be imagining a very isolated existence if he was homeschooled. You need to find ways to address his concerns if you want to convince him. I think this is an older child version of wanting to ride the bus and carry a lunch box, they just want to be *normal* and they think school is the only way to do that.
My DD was 10 the first year we homeschooled and she was convinced she was going to have to stay home ALL the time and never have friends. Having gone to school for 5years she couldn't understand how things would be without it. At first we didn't do a lot and she actually asked to go back to school. Instead of signing her up I asked why and she said she was lonely. So we joined a homeschool group and signed her up for youth league cheer and she felt a lot better about things. DD is NOT a confident, outgoing child but she has done very well in the gentler culture of homeschooling.
I know you said it's too late for next year, but maybe you could look into some options and think about the year after? Don't give up!
