17 of the current 2015 commits have signed financial aid agreements already and will be on campus as students starting in January. Which means they'll participle in spring practice and all and mesh with the before before the rest of the 2015 guys get here in July
If your asking for a list of which 17 are enrolling early I think one has been posted on here somewhere before. But I mean there's only 22 commits right now so most of them.
