As many have said camps are a money grab and it is standard to receive tons of invites after showcases. Hearing “we look forward to working with you” tells you nothing unfortunately. Personal emails w/o reference to a camp are best. I can feel your excitement for ND, but it sounds like a standard one. Have your son keep working hard, prep for higher SAT scores because a 1300 will likely not cut it at ND. He’s only a sophomore they will go up!
D3 will be there later. I would not waste my time on D3 camps if he is that talented. Plenty of assistants at D1 camps will be D3 and he can meet them there. I would advise watching the teams your son seeks to play on. Then investigate their rosters. Be honest with yourself-by looking at the roster is he big enough (of course he may grow but…). Size can be a big factor in D1 college soccer. Check his social media & make sure it represents him well.
