It's easy to look at this in hindsight (and I actually find it strange that someone even had interest in doing so lol), but it's easy to forget at the time that Hatten was never even projected as an NBA draft pick even after his junior year. As others mentioned, he was looked at as a tweener, too short to be a shooting guard in the NBA and not a point guard.
However, I do remember following Hatten after his senior year. I remember vividly how he was invited to play for the Clippers on their summer league team, and Hatten was one of the last cuts when it came time for the roster for the season.
