There are two way to get noticed by College/ University coaches, one way is to be lucky and your team always get looked at. But what if your not on one of those teams you will need a highlight tape. Once the highlight tape is created you will need to create a letter to be sent to the colleges of your choice with the cd of your highlight tape. 

Another option is to send emails to all of the coaches you like with the attachment of your video on youtube. 

hope this helps
