What do we consider as high character?
In the last draft, Samanic turns out not to be a high character guy, but also ends up being a flop, whereas Keldon is high character, but also the best pick at 29.
Kawhi would have been considered high character, but it didn't stop him from ing the spurs over.
Overall, a player's character needs too be factored in, but it can be seen now that the level of professionalism is much higher in the modern era, and there are less starting calibre players in the mould of Demarcus Cousins, Allen Iverson etc, because teams now value chemistry a lot more, and no one player is worth it.
Spurs probably flirted with the idea of talent over character with the Marcus Morris trade deal, but I'm sure they've learned from that.
