That what it would seem like - he's not on NBA radars and no matter how good of a season he has a 23 year old 6'1 - 6'2" PG probably isn't going to get drafted so he's likely looking at this as a way to play on a big stage, earn some money (we probably are paying him 50-100% more than what he was making) and enjoy the experience - and he'll be that much more marketable if he goes back to play in Europe afterward.
Now he could hit the portal after a year of course, so I think we should always consider everyone a one year guy, but if he has a good experience, no reason he doesn't stay for two and play an even bigger role in the offense his second year
