Aren't players taken from the NBA draft treated like free agents and can be signed after 1 July? I'm just guessing. If so, don't draftees sign for 3 years and a standard draftee salary? If that's the case, if Hanga does sign his 4 year deal to continue playing in Europe and after the 4 years, if he's still interested in playing in the NBA, does the aforementioned standard draftee salary still come into play or is he treated as a 'free agent', open to negotiations? If so and he does sign to stay in Europe, kiss him goodbye. Otherwise, sign him and play him in Austin to allow him to get the experience and bring him up if needed, just like Corey.
Life's tragedy is that we get old too soon and wise too late.
