Yeah -
how did all the other teams miss out on him?
Every team in the league could use a player like him.
Other than "he didn't fit the square hole we wanted him to fit into", what did Casspi not have that teams wanted?
His physicality, playmaking abilities, speed, and BB IQ are quantities desperately needed all over the league....
Both Cavs and Rockets tried to turn in him into primarily a standstill shooter on offense. Omri hits FT at a great rate all of sudden, so developing a long-range shot is probably still not out of question for him (he was actually at .350 for his career coming into the season, which is just below league average of .360). Anyway shooting is obviously not his strength as his outside shot has relatively low release point, so Omri needs to be wide open to hit it consistently. But his combination of quickness, length, touch and toughness is more than enough to be an opportunistic inside scorer.
As for his adventures over this summer: he was on non-guaranteed contract in Houston for this year, and was sent out in Asik trade. Omri and his agent glanced over Pelicans roster, and saw a bunch of ball-dominant guards, so it was back to the same role he had in Cleveland and Houston. He asked to be released, and Pelicans did late in July, when a lot vacancies even for backup SF jobs were filled. Plus playing for NT last few years Omri developed a reputation of starting strong and fading late into the season (that's a concern this season regarding Boogie and Rudy as well). In the end Casspi and his agent looked around the league and figured, Kings were the best team to get him minutes. Fans are quick to forget it like a bad dream, but Omri was behind Williams on depth chart to start the season.
