They're just the higher end of what came to mind, which was to orchestrate my original point that Sullivan, though good, can't really compete with those names. Brockington was very good, So was Shayak, Clyburn (was he a guard?) A guy like Chris Babb comes to mind to what you're pushing towards though. He's top 5 on my list anyways.Brockington and Kalscheur deserve some love.
They weren't as good of shooters as most of those guys on the list, but they broke out offensively on a fairly frequent basis. But both of them were two of the best perimeters defenders in school history.
There aren't many better two-way guards (Tinsley certainly is, for instance) on your list than those two.
