Gametime, there are a few ways I could interpret that information. One way is that the DII and DIII coaches feel you are a DI potential talent who might slip through the DI recruiting cracks and they do not want to miss you. Another way, if there were DI's at the camp, is that the DI's, based on that performance, have a different view of your skills at this point than they do.
It is great to believe in your talent. You only have to find one DI coach to believe in it also. But if that does not happen, and they do make mistakes and miss players, then you need to capture the best education and baseball experience by fully investigating the DII and DIII avenue. Personally, I would not look at the DII's and DIII's as something to fall back on at this point. Unless and until you have serious interest from a DI, look at these as the best options and if things change with DI interest, that will be a huge bonus.
