This Hugo situation reminds me a bit of Avery Bradley. Not because they are the same player, but because both could really defend at a young age. Bradley took until year 4 before he really stepped into a scorer's role, and became a legitimate 15ppg player in his prime.
Likewise, I think it would be a mistake to rush Hugo. He's not a great offensive player, which is why he's out there underwhelming at times in a bigger role, on an international squad.
I love his efficiency, and the possibility to see him grow, but I hope we bring him along slowly over the next 2-3 seasons. It still helps us for him to be a really solid role player in the meantime.
