I have no idea if Robinson is a BT level prospect or not, but no doubt that come Spring, teams reach to fill spots. Assuming Schilling is waiting for a "better/bigger" offer than Minnesota, then he was absolutely smart in waiting for Spring as assuming his season doesn't bomb and that he stays healthy, his offer list will grow. Likewise, if Robinson entered the season with offers from Duquesne, Charlotte, and Hofstra, no doubt he'll add a few high major offers to the list as programs like Minnesota, UCLA, etc. lose out on other kids, a kid or two transfer, etc.
It can be a dangerous position to be chasing Spring recruits. As "anonymous" always says, Spring recruiting is like picking up a girl at bar time. You get a little desperate, and the girl often looks a bit better at bar time than she does the next morning.
