Players to take a swing at:
Napier - it's a no-brainer to make him an offer. At the very least, Mason needs the competition. This team needs help with the backup point guard slot, and if Fox goes down with injury for any length of time it really could spell doom for the season if there are no pg additions to the roster. I really don't want Bogs to man that position, as I think he's better at the 2 in a up tempo game.
Harrell - he is a beefy, physical, tough, competitive, high energy motor guy who would complement Giles and Bagley. He killed the Kings last year. Granted, this move would make more sense with one less front court guy on the roster. My vote is for trading WCS. This current team only has one physical "tough guy" presently - Koufos. If the roster stays the same as it is, and Koufos goes down with injury at the beginning of the season, heaven help us. Over an 82-game season I'm not relying on three slender kids (Bagley, Giles and Skal) to be the tough physical bangers that Koufos is, and I'm certainly not looking to WCS for that either.
Hood - He's a versatile two-way player at the 3 and will give some competition to JJ. There's no reason not to take a swing for him. I thought he was was very good in Utah. His best years are ahead of him.
If the Kings want to improve their win total by around ten to get up to the 37 or more win total next year, they must, absolutely must, have a strong bench. They aren't going to win a lot against teams because of their starting five due to the fact that they are young and inexperienced. They need to have a bench that can beat up on teams that may have better starting fives, but weaker benches. All three of the above positions - point guard, center, and small forward need to be strengthened before the season begins. If they aren't strengthened significantly, I will have doubts about the success of the upcoming season.
