Rush is one of the biggest unknowns there is. There's no video of him, scant little coverage, and only really one picture;
Billy comes from Robert Morris; not the Northeast Conference school from Pennsylvania, but the NAIA school from Illinois that also gave birth to Othyus Jeffers. Rush wasn't even the scoring leader at Robert Morris, his 16.1ppg trailing someone called Robert Jones for that crown. But he did grab 7.7 rebounds per game, good for second on the team, and also shot 41% from three point range while taking more threes than twos. Milwaukee worked out Rush before the draft - I think they were the only team that did - and they clearly liked what they saw. As a 6'7 wing player with athleticism and an outside jumpshot, you can see why.
