That would be a really small lineup.
I think we need to get over our fear of small ball lineup. The Warriors just won the championship by starting a 6'8'' guy at center (no, I'm not comparing our team stuck in lottery with the team that just won the championship), while their primary center didn't play at all in the final game, and sparingly, as they won 3 straight.
And it wasn't just this series. They were at their most efficient with that lineup throughout the year.
While Ws are a special case, with multiple good defenders, several teams employ small ball(ish) lineup for extensive stretches. Some of them play big, but lot of their "bigs" play away from the basket. Plus, how many SFs in Western conference are major scoring threats, or big guys that can play above Winslow? KD, Kawhi, Batum. One can probably add Parsons, Iggy/Barnes to this group, but I don't think his height will be a disadvantage against any of these guys except KD.
I think the kid has a chance to be special. In a few years, he can stay on the floor just for his defensive capabilities, while providing energy, athleticism, and decent offense. He recently won the national championship, where he was often the best player on the floor. I personally hope we pick him.
