Looks like Spurs didn't draft their main targets but were more than happy with what they got.
Probably they had hope to trade up to take Hachimura who was probably their main target based just on consistency (I don't buy they were targeting Cam Johnson) and probably they preferred by a bit Doumbaya and Bitadze over Samanic, but the first went too high drafted and they had no chance to a deal for n° 9, and the others were seen quite just as an alternative to Luka (that was a better fit) as stretch bigs, but only by little.
The fact that they had KJ high considered as a sf is enough to call the draft a success.
I'm just sorry they did not draft Roby (that they scouted and nauseam and was my favourite to take based on 3 and d potential) with the second round...but probably with Luka already drafted he has been considered redundant and not worth on spending any asset to improve the second round draft position...
