Berggren begat Kaminsky begat Happ. The point being that we heard the year before Kaminsky broke out how much trouble he was giving Berggren in practice and then that Happ was holding his own against Frank. Maybe Ford is the next guy in line, but other than Kaminsky who didn't break out until he was a junior, the other guys tend to break out the second year in the program (whether as sophomores or redshirt freshman). That didn't happen for anyone this year and it's a huge concern.
Happ, Iverson, and Trice are the obvious starters next year with Trice being the only outside shooter you'd trust at this point. It will be real test of Gard's ability as based on what seems to be coming back, they will be hard-pressed to finish over .500 let alone keep their NCAA streak alive.
