I think it's good that he declared. The younger you get into NBA the faster you adjust to NBA style of basketball. You can be a star in other leagues, but it still takes time to get used to the NBA. For example, Nikola Mirotic was a Euroleague star, yet he also had an adjustment period when he got into the league. However, one argument for staying at Gonzaga for the third year could have been Domas developing his long-range game. He won't get an opportunity to shoot threes in the NBA when he almost hasn't showed that at NCAA level. I imagine him being used exclusively as an energy big off the bench for a first few years of his NBA career, until he shows he can bring some other things to the table at the next level.
