This late in the game it would be hard, if not close to impossible, for an unsigned senior to be formally "recruited" to play at a school. That said, if you were really REALLY dedicated, you should contact the coach at your intended school and ask about walk-ons. Most schools (particularly D3's who give no aid), have a walk-on tryout during the pre-season. These can be extremely competitive (in my experience) and the kids often don't have a lot of time to show their merit. It is possible to get a spot though and I have seen it happen more than once. Time is of the essence and the sooner you get in contact with a coach the better. Make sure they understand your intentions. Don't be afraid to be blunt and ask questions (like will you actually have a chance). If you want it bad enough and show your talent, then a good coach will have no reasonable answer as to why you shouldn't be on the team. However, you're also competing against the "recruits" and will have to be spectacular in order to replace one's spot, as a college team is only allowed so many men on a roster. Even if a walk-on doesn't make it the first time around, I've seen a number come out in the spring or at a later year and make it. Best of luck to you if you're going this route. Don't give up just because it's hard.
