no one can "sign" with a college until the national signing day. i believe it's some time around the 1st week of february. you can verbally commit to a school prior to that date. also, there is only a "signing" for a division 1 & 2 program within the college. division 3, naia, patriot & ivy league schools have no "signing" because they do not provide any athletic scholarships for athletes. so you can tell those schools that you plan on playing for them but you still have to attend a tryout before the season begins.
