Iowa has started 4 white guys all year: Horner, Haluska (one of the most athletic players in the country), Brunner, and Hansen.
it would be tough for Iowa to start 5 white guys, however, because their team roster consists of only two white perimeter players (Horner and Haluska) who regularly see minutes. all of Iowa's big men are white, though. so if the Hawkeyes were to go all-blizzard, Brunner would probably have to move to the three so talented sophomore forward Alex Thompson could play at the four with Haluska sliding to the off guard. as i said, this incredibly big line-up is unlikely to happen.
as for Sean's redundant question about a movie being made, the answer again is very unlikely.
