I do not see how this signing of Omri Casspi can be bad in any sort of way....
It's a low risk signing, Casspi will not earn a significant amount of money from the Kings and he is only signed for one year, which means the risk is totally minimal.
Casspi was a member of the Kings for two straight seasons, he was picked in the draft by the Kings, his best season thus far was his rookie season where he played for the Kings, as a matter of fact, Casspi was very productive when played with the Kings, especially in his rookie season, he was playing with a lot of heart and enthusiasm and were running a lot on the court, Casspi has regressed in his second season with the Kings, I remember he was frustrated with coach Paul Westphal, but to be honest Casspi is a mediocre player in this league, but I was reading lots of comments here saying he is not talented enough for this league, it is definitely incorrect, Casspi is a decent bench player in the NBA, he is suitable player to come off the bench a contribute to the team, Casspi is a legitimate player in the NBA, this is why this is his sixth consecutive season in this league.
But don't get me wrong here, I believe Casspi was doing a mistake by deciding to leave the Kings, in retrospect I really reckon the trade request from the Kings has really affected his career, he landed in Cleveland where he finally comprehended how tough is to survive in the NBA, but I also think it molded him as a person and as a player, I think he is more mature and wiser than he was in the beginning.
To be honest, I think Casspi still has a lot to contribute in the NBA, I think him reuniting with the Kings is a smart move, his best days were with the Kings, and I sincerely hope we will be witnessing sparks from his rookie season.
