I vaguely remember discussions about there being something mental about him as well. But I don't remember what it was. Other teams backed off, and the one team that didn't already had a starting point guard for the future. Haliburton isn't even a PGOTF for the Kings.
Yeah, I remember those too. Plus he missed the end of the season for an injury (broken wrist, broken hand?) and his agent refused to provide medical information to most teams. We did the right thing.
He looks great compared to who we selected (so far) but I truly believe that had we selected him we'd still be in search of a starting PG in a year or two. I don't think his ceiling is all that high. IMO his ceiling has him good enough to start but just barely, not the difference maker most contenders are searching for.
