Kings already have guys who can create for others: Cousins, Evans, IT. You surround such guys with role players who finish plays and defend. Problem is most guys Kings have are either bad finishers(or refuse to play as such) or bad defenders. Out of 4 "great" (no, .358 or .372 on mostly open threes are not great) shooters only Patterson can be called an average defender. MCW is really bad at shooting from anywhere, and I guarantee you teams will allow MCW penetrate and dare him to finish - even minimum resistance can cause him trouble.
I guess we have a different way to look at the basketball game. In my opinion, Cousins and Evans are the two guys who need to finish plays. They should be the focus of our offense, not our role players. For sure Evans can create, but he should look for his offense first. DMC just needs to finish inside, I really don't understand why he should create for others. IT... Well, if you really think IT can create for others, we are probably looking at two different sports. IT can create, sure. He can create his own shot. He is not a willing passer, he is a PG who loves to shoot and keep the ball in his hands. He can help our team, but I can see him in a Nate Robinson role. It's definitely not the starting PG I want for this team. Then, you are right. We need role players who play D and hit shots. But they can't be the focus of our offense.
I also would like to point out that we have shooters, and pct doesn't mean anything for our players. What kind of shots have they been taking? It looks to me that most of the shots our players are taking are off the dribble, contested, self created. If you have a PG that can actually create shots, giving the shooter the ball in the right spot, at the right time, you can see the pct going up significantly. Rhythm is vital for a shooter. MCW could be the kind of role player we need. We don't need another player who needs shots to be effective. We need a willing passer, a good defender, with quick hands, and most important thing, SIZE!!!
Sure he is a bad shooter, but so is Rondo. Kidd was awful when he first came into the league. You can improve shooting. You can't improve size and the will to share the ball.
BTW, I'm also not so sure that all of our players are so bad defensively. Sure, Jimmer is the worst defender in the league, but when it comes to guys like Thornton, Patterson and even JT, I think they could be average/decent team defenders. We can't have a good idea because we've never had a defensive minded coach. Do you think Thibs couldn't turn MT or JT into good team defenders? He did it with Korver, Belinelli, Boozer, etc. They are not great defenders, but they are good enough in a concept of team defense.
