Having just seen several of son’s friends and a few teammates leave their D1 school after one year I would say that would not matter at all.
I say that because kids either go to D2 or D3 or if they want to stay at D1 they almost all go to a juco for year 2. Many of these transfers are supported/encouraged by their original college coach. That coach will help them or I have seen several go to jucos that recruited them out of HS as well.
Also a lot of these kids have a body of work from year one. Those results matter too.
