At this point, Jose has really just two options. Play another year at GT or follow his dream to play in the NBA.
Since I also dreamed of playing in the NBA, I understand how that can drive people to be in the gym at 5 AM and on the track running intervals. But no one (hardly) dreams of playing pro basketball in Israel or Spain. Not that those are bad options. Those are just not what most guys playing hoops their entire lives dream about.
I am sure Jose has heard scouts tell him he is not likely to get drafted, but he can try out for the G league at the minimum salary and see how it goes. He may have had talks with international scouts. But, at some level he probably has to face the fact that he will not get a guaranteed contract next year. Or maybe ever. My guess is that he is seen as a 23 year old 6' PG trying out for a league that has 6'9" PGs. KD is almost 7' tall and essentially plays the point for the Nets.
He knows he is as good as almost all the players in the G League Elite camp. But, most of those guys are in the same position he is relative the NBA. If he returns to GT he will almost from the start be a favorite for ACC POY. NIL money will likely be more than the G League or Israel would pay him.
