Hausen's assist rate is certainly a lot lower than Spencer's was throughout his career pre-UConn.
But also despite taking a bunch of 3s (which are assisted at a high rate), Nova had like a D1 average assist rate as a team. Neptune doesn't know how to teach passing.
But either way, I expect us to use him more like Hawkins and less like Spencer. Another big thing is that Hausen may be willing to come off the bench (at UConn at least), which is rare for a transfer. Obviously that's all speculation based on the smoke, but if we want to keep Ball on the team, he's likely to require starter minutes.
