As others have said, nothing to worry about now...today's baseball culture makes players feel like if they are not getting offers as a Junior, then its not going to happen...heck, our high school had three graduated seniors get offers to play just in the last couple of weeks of June (after graduation!).
If you can play, coaches/schools will come and go through your life...you will not always know what they are thinking. Some that seem really interested may dissappear without a word. Others that you didn't even realize knew who you were will show up with the most interest. At this point, keep you options open. Be willing to look at/talk to everybody. Too early to be worried about every game a coach does and doesn't come to or whether every email is answered. Just keep doing your thing.
If you can play, if will happen.
Take care. Sorry for the long post, I was just in the mood to ramble!
